cmsAdminWebServer doesn't work - TypeError: an integer is required (got type bytes)

[BeatriceSmart1e]

I've got a small issue, running the cmsAdminWebServer command just gives me an error:

File "/usr/lib/python3/dist-packages/gevent/_tblib.py", line 202, in as_traceback
    code = CodeType(
TypeError: an integer is required (got type bytes)

Here's the entire error message, if it helps:

I have tried running cmsResourceService -a, but I can see on the log that AdminWebServer loop-restarts.
This is the first time I'm encountering this issue, I have used CMS before and never seen an error like this - everything worked smoothly.

Hi, is it possible that you configured a port in cms.conf as a string instead of a number (e.g. admin_listen_port here?

Alternatively, are you using the correct gevent version (20.12.0)?

[BeatriceSmart1e]

Hi, I have all ports as integers as it was by default, and the gevent version is what is should be (20.12.0).

gevent/gevent#1491 could this be relevant? Possibly you have the listening address to be resolved and DNS does not resolve it?
