Re: Bad Gateway error 502 - Upgrade to iRedAdmin-Pro 4.4 from 1.3.1

Shortly after this post iRedMail became unresponsive, now also unable to log into roundcube .

Rebooted the server but no change

Re: Bad Gateway error 502 - Upgrade to iRedAdmin-Pro 4.4 from 1.3.1

UPDATE: Roundcube issue solved, IP was blocked by firewall (probably because have set up one incorrect password & tried too many times), however I can't fix it because I have no access to IredAdmin still, error 502 persists...

Re: Bad Gateway error 502 - Upgrade to iRedAdmin-Pro 4.4 from 1.3.1

hi @gkampou,

Sorry about this trouble.
Please visit iRedAdmin-Pro again and check immediately:

- show us output of command "service iredadmin status"
- show us last 30 log lines of /var/log/syslog.

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?

Re: Bad Gateway error 502 - Upgrade to iRedAdmin-Pro 4.4 from 1.3.1

Did you access iRedAdmin-Pro first? Seems not right.
Please show me output of commands below:

curl -k https://localhost/iredadmin/
service iredadmin status
tail -30 /var/log/syslog

Re: Bad Gateway error 502 - Upgrade to iRedAdmin-Pro 4.4 from 1.3.1

For the previous output, I had accessed IredAdmin-Pro first from a remote machine by browser. Using your instructions above I get:

#curl -k https://localhost/iredadmin/

<head><title>502 Bad Gateway</title></head>
