Hi All,
Working on Dell laptop, using the browser Firefox. The Internet is working and I am able to open my gmail account. Firewall is disabled. While I am able to open certain websites like my bank account and this forum, most other websites do not open. I am also not able to open links that I receive in my emails. Firefox shows the message or error like given below: "Unable to connect
An error occurred during a connection to isbn.gov.in.
The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web."
Need help to resolve the issue please.
Regards,
rsp2
Hi,
I changed the profile but still getting the same error:
"Unable to connect
An error occurred during a connection to isbn.gov.in.
The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web."
When you say the internet is working, do you mean that you’ve been able to access the specific sites that aren’t working, using another browser? That particular server you give as the example, ping isbn.gov.in, responds to pings, so you could try pinging it in a console. This establishes not only that the DNS is resolving but that you’re able to reach that box (i.e. there isn’t a routing problem in-between.) Sometimes there can be a routing problem on the internet and certain sites or services work but not others, so you need to establish that a specific site is not working only in Firefox but works in another browser, before you can narrow it down to a problem with Firefox.
If you can view a specific website in another browser, and not in Firefox, the first thing I would look at is the proxy settings. Firefox allows the overriding of system proxy settings and establishment of custom settings. Usually, these are profile-specific, however, so if you have created a new profile it would presumably reset this to default to the system settings.
If that failed, I would assume that something might be broken about Firefox and I might uninstall and reinstall it as the next step.
Hi,
The problem seems to be with Firefox because I could access the website https://isbn.gov.in from my android cell phone.
The codes are as below:
rsp@localhost:~> zypper verify
Root privileges are required to run this command.
rsp@localhost:~> sudo zypper verify
[sudo] password for root:

Could be — but not necessarily! Because: do you actually use the same internet connection for both your computer with Firefox and your android cell phone (with which browser)?
It’s nice that it works on your phone, but you should investigate this issue on your computer (that computer, that internet connection).
firefox -p or about:profiles and create and use (make sure to really use the new profile) a fresh and clean new profile to eliminate any Firefox specific settings made in the past
rpm --verify --all | grep 'missing' as root (like mentioned by another user — is (Firefox) install broken?)
use a different browser on those(!) specific websites on that(!) computer with that(!) internet connection (not your cell phone) — you can try links (it’s minimal) first and then Konqueror (it’s quite basic) (do those websites actually work on your computer at all?)
ping <websites_used_to_work> (also mentioned by another user) (do you have any access to those websites on your computer at all?)
Do run all those 4 steps in that order.
If it’s an “easy” Firefox issue, step 1 should be of success.
If Firefox is broken by install, step 2 could indicate this.
If it is somehow Firefox related, but your computer is OK (OS and system settings) and your internet connection is OK, step 3 should work.
If all 3 steps before are not of success, step 4 is of interest. When you don’t get answers for your ping commands, you have to further investigate on your connection (i.e. your connection as it, your modem/router, your computer with its network settings). Then the result of your cell phone can get of interest.
And not to forget: please explicitly answer if you use something like Proxy or VPN (on your computer, or even in your router)? Disable them (at least temporarily).

Installed Konqueror. There also, the same error persisted.
Well, then it seems not only Firefox related… When you tell you have the same issues with Konqueror…
Good to hear. That makes it much easier in general.
I guess it’s something network related then. Still to find out if system’s settings related or depending on your connection itself.
Use ping as this:
ping www.google.com (Google main site)
ping 8.8.8.8 (Google DNS)
ping isbn.gov.in (website you mentioned)
ping <other_website> (other sites you assume that should work — but without https://, just the domain, like www.google.com above)
Try ping for the websites (several ones, please — and for for checking purposes www.google.com and 8.8.8.8) you assume that should work. Do you get positive or negative results?
And to make it clear and not to get confused:
How do you access this forum? (What device, what internet connection? Are they different or the same?)
You told that you installed Konquerer and reinstalled Firefox… So, the software management on your system is actually working properly? (You can install/reinstall software on that(!) system using that(!) internet connection?)
(Please, explicitly answer these two questions, especially the second one.)
Just to be really sure… Please post the results of:
cat /etc/hosts.deny
cat /etc/hosts
You seem to have partial internet access. Some sites work, others not. Like you can get software from openSUSE and access some sites. But you cannot access specific sites.
You refer to many Indian websites… Can you tell where you are? India? Pakistan, but using Indian websites? Or similar? Maybe, sites/addresses are blocked in your country/ by your ISP.

I am located in Delhi India’s capital.
No these sites are NOT blocked in India. I have my login credential on all these sites and I could access them as and when needed, before this error began to happen.
The other 'investigative ’ action I have not understood. From where to get it. When I click on these I links the same error occurs like ‘NOT ABLE TO CONNECT’ etc.
cat /etc/hosts looks almost good: it seems not to be standard… And I really wonder where the following come from, they are not standard:
192.168.1.8 dell-linux
192.168.1.5 dell-linux
So…
no Proxy (as you told)
no VPN (as you told)
software management by openSUSE does work
you can access some sites
you cannot access some specific sites (even ping does not work…)
/etc/hosts.deny looks good
/etc/hosts looks almost good (wondering about those two entries…)
as you told, you have tried a fresh and clean new profile in Firefox (so, any settings or cache don’t matter)
and you have tried a second browser (Konquerer in this case)
right now, you cannot get this tool called OONI: it’s on GitHub, no big thing. But you can also not access that site…
For me, it seems that some (many?) sites are blocked. But right now, I cannot tell if they are blocked on your computer (inside) or in your internet connection (outside).
Are you aware of other network related settings on your system:
have you set a special DNS configuration? (actually, there are several ways to set up a specific DNS on a machine…)
have you set any special network configuration at all?
have you set any special general configuration at all?
could it be that someone had access to your computer?
Maybe, I have a further idea or we do need more help.
(Now, it could be worth giving VPN a try: if you then can access those specific sites. But maybe, it’s too late for VPN. We have to find out, where the blockings come from.)

Well, it seems IPv4 vs IPv6 related! Probably, you are not blocked by your ISP due to country law enforcement. Probably, it’s the IPv4, IPv6 setting in your router or at your ISP.
That’s also why you can use your cell phone, but not your computer.
We do have now the probable reason. But I don’t really know how to proceed. Sorry. At least, you have a clue.
Please, check if you or your ISP recently modified your router or your connection.
