[SOLVED] Web gui - ERR_CONNECTION_REFUSED [solved] fail2ban

[Didier Misson]

Hello
Proxmox 6.1-8
Web GUI interface stop to reply.
I don't know exactly when.

ALL seem ok : containers run. Web sites are available... (so not very critical... we are up)
but I cannot manage Proxmox thru Web interface.

ERR_CONNECTION_REFUSED

I try with Firefox and Chrome : no connection.

I reboot the Proxmox server : doesn't change : https://Web gui:8006 always not reply.

Disk is not full.
all seem normal.

What can I check ?

Thanks.
Have a nice WE.
Didier

I try some debug :

netstat -apn | grep 8006
tcp 0 0 0.0.0.0:8006 0.0.0.0:* LISTEN 1688/pveproxy

I look to the log....

ohhhh...
shame on me

Probably some login errors...
