Are the ports 8120, 4500 and 443 not answering or not listening on the server, so can you see the ports with this command on the GMS server and if so what is the process that owns these, this should be python3

ss -pant | grep -i listen

Also are there any clues in the logfiles in /var/log/datasync and the subdirectories that hold the logs for the different parts of GMS

when I say not open I mean not listen

in the meantime I'm gone through MCHECK

Everything looks fine until the general health check

says Checking Mobility Services...     Failed but where to find the reason

and Checking Server Date...           Failed what is not correct as time of all servers is synced to a local ntp service which is synced to an internet database

One step further the /var/log/datasync/webadmin/server.log leeds me to a certificate problem, the gms_mobility.pem had the private key missing, so I fixed that and console comes up

Most things seem to run

can connect to console

incomming mails arrive at groupwise-agent and mobility-agent, can see in logs under debug condition

but General Health Check says all passed as off Checking Nightly Maintenance...   Failed

and I still can notconnect my adroid phone to the system

I configure it the same as a connection to a same system at customer site which isworking

Still can not connect my android phone even in the internal privat lan, on port 80 security disabled.

Is there any way to check if connection is possible. If I connect with a bowser I got the message im am not allowed

thanks for all the help

Hey Rainer,

it looks like you went through a lot in the last couple hours...

When I'm testing GMS internally i take the windows mail app from Windows 10 and connect via IP

You have to user SSL on 443. At least thats what I'm using all the time...

If you use an Android device, use Gmail APP for Active Sync... In my opinion works best

You are right, when you open a browser on https://gms_ip you should see 403 forbidden

Any hints in /var/log/datasync/connectors? 

I try to add an account in gmail, the same way it worked at customers site, but no success on my site

Sorry no windows just mac and linux (suse and debian) and android 7 android 13 on smartphone and android 12 on tablet.

But I can easily install win 10 trial in a VM

Thanks 

Rainer

Thanks to everybody for help and hints. I learned a lot. but still no smartphone connection. So I decided to do a brand new start with all the knowledge I got

Rainer

I am turning in a circle, returned to the original certificates for admin service, giving me the browser error, but ok

setup a new sles15 sp 4 installed GMS 18.4.2 and I get the error from the beginning 

AttributeError: module 'lib' has no attribute 'OpenSSL_add_all_algorithms'

all python modules were installed by install.sh

Sorry me again.  I started up from scratch installed again a new SLES 15 SP,

just Base System, Desktop Apps, Server Apps, SUSE Hub, nothing else, updates no patches.

then 'find / -name "*pytho*"' and found a lot of python 3.6 modules installed

As of MRosen, if I understand it right noPython should be installed
