Hi Expert (atlassian-jira.log) ,
I was unable to access my system at yesterday. When we try to access it appear an error called “Proxy error”.
Could you tell me what caused it?
Have a look screen shot below and let us know the update.

we can access using localhost and when we try to access using base url then appear this error.
I have been checked the attached log file but didn't find any issue.Could you please check this attached log file and tell me what was the reason?
Thanks
Mohin
