Same problem as william_jmr, also replied on that post with logs below



Just had exactly the same problem. Service status shows:

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

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.

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/
<html>
<head><title>502 Bad Gateway</title></head>
<body>
<center><h1>502 Bad Gateway</h1></center>
