Topic: Internal Server Error - Iredadmin

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version (check /etc/iredmail-release): 1.3.1
- Deployed with iRedMail Easy or the downloadable installer? Standalone
- Linux/BSD distribution name and version: Centos 7
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MySQL
- Web server (Apache or Nginx): Nginx
- Manage mail accounts with iRedAdmin-Pro? Yes
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.
====

After recent server update I am unable to access the Admin panel. I have the "internal Server Error" message.

Logs:

 uwsgi: Traceback (most recent call last):#012  File "/usr/lib/python2.7/site-packages/web.py-0.51-py2.7.egg/web/application.py", line 290, in process#012 return self.handle()#012  File "/usr/lib/python2.7/site-packages/web.py-0.51-py2.7.egg/web/application.py", line 281, in handle#012 return self._delegate(fn, self.fvars, args)#012  File "/usr/lib/python2.7/site-packages/web.py-0.51-py2.7.egg/web/application.py", line 527, in _delegate#012 mod = __import__(mod, None, None, [""])#012  File "/var/www/iRedAdmin-Pro-SQL-3.9/controllers/sql/basic.py", line 15, in <module>#012 from libs.sqllib import utils as sql_lib_utils#012 File "/var/www/iRedAdmin-Pro-SQL-3.9/libs/sqllib/utils.py", line 10, in <module>#012 from libs.sqllib import user as sql_lib_user#012  File "/var/www/iRedAdmin-Pro-SQL-3.9/libs/sqllib/user.py", line 19, in <module>#012 from libs import mlmmj#012  File "/var/www/iRedAdmin-Pro-SQL-3.9/libs/mlmmj/__init__.py", line 7, in <module>#012 import requests#012 File "/usr/lib/python2.7/site-packages/requests/__init__.py", line 58, in <module>#012 from . import utils#012 File "/usr/lib/python2.7/site-packages/requests/utils.py", line 25, in <module>#012 from . import certs#012ImportError: cannot import name certs

When I initially saw this error, I upgraded web.py from 0.39 to 0.51 as suggested in a previous post. However, I still get the "Internal Server Error."

Any ideas of how to solve this?

Re: Internal Server Error - Iredadmin

Please install Python 3.8 instead of 3.6.

yum install python38 python38-pip
pip3 install web.py==0.51

Re-run the iRedAPD AND iRedAdmin-Pro upgrade script, pay attention to the console output, it should finish without any error.

After switching to python38 I get the following output after running the upgrade_iredapd.sh

Still have the internal server error on iRedadmin-Pro3.9 (this is the latest version I can use).

Re: Internal Server Error - Iredadmin

You're running CentOS 7? oh dear, what a big mistake i made.
On CentOS 7, only Python 3.4 and 3.6 is available, we'd better use 3.6.

yum install python36 python3-pip
pip3 install web.py==0.51

So sorry about this. sad

I removed all versions of Python3 from my system and ran upgrade_iredapd.sh again and this time there were no errors. However, I still have no access to iredadminpro-3.9.

Something else must be broken.

Iredadmin is running, I just can't connect to it

Re: Internal Server Error - Iredadmin

This was solved by @ZhangHuangbin with the following:

 rm -rf /usr/lib/python2.7/site-packages/backports.ssl_match_hostname-3.*
yum reinstall python-backports-ssl_match_hostname
yum update
