Unable to access GUI since upgrade on 7.2.10

[Sylvaner]

Hi,

Since my upgrade from 7.2.9 to 7.2.10, I encounter somes difficulties to access certains parts of the GUI.

I reach access to the firewall after a lot of time (5 minutes).

I can't upgrade to 7.4.X because the GUI crash too (No upgrades available).

Is there any way to solve this problem ? (Probably WebSocket).

Best regards

Hi Sylvaner

Can you try from browser's private window? Or use another browser (Chrome or Edge).

Yes, i tried with Chrome, Firefox, Brave and Edge (Private too).

And another computer.

Please check this article for troubleshooting checks.

Try to kill httpsd daemon : fnsysctl killall httpsd
Try changing server certificate.
I would also suggest to give https access to other internal interface just for testing purpose and monitor the behavior.

Thanks, I tried the different possibilities but it didn't change anything.
I ended up rebooting the cluster, a big scare with a desynchronization, then after rebooting the second member everything went back to normal.
