FreePBX Webserver error, works only for a bit after restart

Hi Guys,

I’m new to the forum because i could not find any solution to my problem anywhere else. A week ago my freepbx run smoothly and there is no problem.
and from yesterday i got a problem in my freepbx, i can’t access freepbx through web portal (pbx ip address) but everything else working. so i restarted my server, i can access it but for less than a minute. I could see on the Webserver status go from “OK” to “timeout” and then “error” thus making it in-accessible again.
Could it be a port issue? can someone please help me?

I also looked at the Asterisk logs, here is the logs :
