Problem with Plesk Panel access

[PayamK]

Hi,

We have dedicated server with Parallels Plesk panel 11.5.30 licensed version installed!
every thing on the server works fine but we lost access to Plesk administration on port 8443

IP tables work fine!
psa services work fine!
all websites on the server works fine!

but we can't access to administration panel, and this happened on no reason.
I can't understand what happened to our Plesk panel.

Thanks for any suggestion.
Best regards

Hello,

I think your server firewall is blocking the access of you admin panel, Try to stop the iptables on your server and check it

i checked it and it's working fine.
i think i found what cause a problem.
when i checked my server listening port via comment:
netstat -nlp | grep 8443

I see nothing, after that I'm trying to start sw-cp-server service and output is:
Starting SWsoft control panels server...nginx: invalid option: "f"

so i checked my log files using :
tail -f /var/log/sw*/error_log

and i'm trying to solve using bootstrapper:
/usr/local/psa/bootstrapper/pp11.5.30-bootstrapper/bootstrapper.sh repair

but nothing happened

thanks for the reply
