What is the best way to stop "Server did not provide gRPC service configuration in time error on boot"?

I keep getting on and off “Server did not provide gRPC service configuration in time” error on boo? I am unsure whether this is a hardware or a software issue. It basically means that my Gnome system does not load or ask me for my password for my keyring, so my e-mail client (Evolution) then fails to connect. Sometimes it works if I re-boot but today it is doing it twice. I have about three things set to start automatically could this be interfering with it. Has any one else come across this problem - I couldn’t see anything in the forum .
FWIW this is what Chat GPT had to say on the subject do any of these suggestions make sense?
The error “Server did not provide gRPC service configuration in time” typically occurs in systems utilizing gRPC when the server fails to deliver the service configuration to the client within the expected timeframe. This issue can happen for several reasons, including misconfigured gRPC servers, connectivity issues, or timeout settings.

Here are some steps to diagnose and resolve this issue:


1. Check Server-Side Configuration

  • Ensure the Server is Running Properly: Verify the gRPC server is up and correctly listening on the expected port.
  • Service Configuration: Confirm the server is properly configured to provide service configurations. If you’re using an xDS-based setup, ensure the control plane is working as expected.
  • Startup Timing: Check whether the server startup is delayed, causing a timeout for the client attempting to fetch configurations.

2. Increase Timeout on the Client

  • On the client side, increase the timeout for the configuration fetching process. Depending on the language or library, this could involve setting an appropriate deadline for the gRPC call.
  • For example, in Python:
    import grpc
    
    with grpc.insecure_channel('server_address') as channel:
        stub = MyServiceStub(channel)
        response = stub.MyMethod(request, timeout=30)  # Set a larger timeout value
    
  • Similarly, configure the timeout parameter in other languages accordingly.

3. Network Issues

  • DNS Resolution: Ensure the client can resolve the server’s hostname to the correct IP address.
  • Firewall and Security: Check for firewalls or network policies that might block or delay communication between the client and the server.
  • Latency: Monitor network latency, as excessive delay may cause timeouts.

4. Verify Service Configuration Delivery

  • If the server provides service configurations dynamically (e.g., through gRPC-LB or xDS), ensure these configurations are accessible and correctly delivered.
  • Enable Debug Logs: On both the server and client, enable debug-level logs to trace the issue. Look for specific errors related to fetching or parsing configurations.

5. Keepalive Settings

  • Misconfigured keepalive settings might cause connections to drop. Adjust keepalive parameters to ensure the connection remains active:
    • Client: Increase keepalive time and timeout.
    • Server: Allow the keepalive pings within acceptable intervals.

Example in Python:

channel = grpc.insecure_channel(
    'server_address',
    options=[
        ('grpc.keepalive_time_ms', 10000),  # 10 seconds
        ('grpc.keepalive_timeout_ms', 5000)  # 5 seconds
    ]
)

6. Verify gRPC Library Versions

  • Ensure both the client and server are using compatible versions of the gRPC library. Incompatibilities might cause issues with service configuration fetching.

7. Implement Retry Logic

  • Add retry logic in the client to handle transient errors. Libraries often provide built-in retry mechanisms or allow you to implement custom retries with backoff.

8. Fallback Options

  • If service configuration delivery remains unreliable, consider using static configurations on the client. This avoids reliance on the server for dynamic service configuration.

Troubleshooting Steps

  • Collect logs from both client and server for detailed error messages.
  • Use tools like tcpdump, Wireshark, or netstat to verify network connectivity and server reachability.
  • Test the connection manually using a simple gRPC client or CLI tool like grpcurl.

By following these steps, you should be able to diagnose and resolve the “Server did not provide gRPC service configuration in time” error effectively. Let me know if you need more detailed help for your specific gRPC setup!

Are there any thought on this? Problem is back again after DUP update yesterday to : # System Details Report

@jjis Hi, nothing gRPC related installed here zypper se -si grpc or are you running an application of some kind on startup?

Hi Malcom, thank you for taking the time to reply in those circumstances (it relates to the password locker or wallet for Gnome online accounts I believe). On searching some more info I saw some reference to Proton Bridge app in relation to this which I had in my start up list. So it could be related to that, although in the past I removed that from start up and still had the same issue. I have a couple of cloud storage services daemons to autostart, so I guess it could be one of those?
Or I wonder if it could be the Opensuse Welcome Screen? I cross that off in Tweaks so it is not is auto start, but the next time I start up it pops up and puts itself back in the autostart. The only way I can stop that coming up is to untick the box on the Screen would that stop it running at start up or is there another / better way to manage start up programs as I could find anything in YAST. Sorry for the verbose reply.
Jamie

On running the zypper se -si grpc command you mentioned I get the following output:

@jjis your list of applications is most likely the culprit… When it happens, I suggest opening a terminal, switch to root user and look at the output from journalctl refine the ss command to see what is opening ports etc.

So I have no grpc related packages installed here…

OK thanks for the advice, I’ll try that next time it happens. I’ll leave this open for now in case I find an answer or solution which might help others if they have the same issue.

Happened again, not sure the journalctl command helped seems to give thousands of lines and goes right back in time to Nov 29 & an old kernal 6.11.8-1 rather than the current one 6.12.10-1 that is running. Or is it from whne it was originally compiled?
Eg first line is Nov 29 16:53:15 OSCobra kernel: Linux version 6.11.8-1-default (geeko@buildhost) (gcc (SUSE Linux) 14.2.1 20241007 [revision 4af44f2cf7d281f3e4f3957efce10e8b2ccb2ad3], GNU ld (GNU Binutils; openSUSE Tumbleweed) 2.43.1.20240828-2) #1 SMP PREEMPT_DYNAMIC Thu Nov 14 12:54:01 UTC 2024 (099023b)

@jjis use journalctl -b --no-pager | grep gRPC the -b is for this boot up, no -b should troll all the current boots etc. There are many options to refine your search. Suggest you either use journalctl --help or the man page…

Ah thanks for that, looks like it is mostly the Proton Bridge thing even though that was now not on auto start seemed like it might have been waiting for it, which is weird. Probably my system / set up rather than an OS issue. So I’ll leave it up here for now to roll off assuming no one else has similar issues.
