Hey guys,
Figured would share something that could potentially help others if you were to ever encounter this problem. Worked with customer on upgrading their 3 member cluster from R80.40 jumbo 161 to R81.10 jumbo 94, but I totally forgot the fact he told me they had one member where web UI would log them in, but then as soon as they went to any tab, it would log them out and even clish / ssh commands would be very sporadic.
They dont know for sure when this happened, but at some point in R80.40, out of the blue and it would affect all users, not just admins. TAC told them to do cpstop/cpstart, reboot, soft shutdown, confd restart, nothing helped. Even trying all sort of browsers (even incognito mode) did not make any difference.
We ended up doing hard powercycle and that solved the issue, so we were confident upgrading afterwards.
Anyway, thought would share this, so if anyone ever faces this problem, thats easiest way to solve it.
Cheers.
