This is the EXACT error number that is being posted in other threads.
So, to me, this is NOT a problem with Chromium. The other thread that is current, is NOT related to your website, but to the Google Messages sync. Let me find it.
There … if you read in that thread, there are users with problems with “error 159” using Chrome. Personally, I do not have an issue with Chrome (but I am running Leap 15.6). You will see i’ve posted in that thread too.
I would say, use the Flatpak version until the problem is found in TW.
