I am currently running Tryton 6.0.12
Sorry for causing the confusion with the IP addresses.
10.0.0.124 & 10.0.0.82 are my Windows client PCs.
I have diagnosed the problem now myself.
It is a Tryton error, my network (configuration) is fine.
The following error is the cause of my client not beeing able to connect to the server:
Sun Sep 10 12:29:37 2023] DEBUG:trytond.wsgi:Exception when processing <JSONRequest 10.0.0.82 'http://10.0.0.203:8001/' [POST] common.server.version>

return conv(self.get(section, option, **kwargs))
ValueError: invalid literal for int() with base 10: '2MB'
changing the value in the trytond.conf from max_size = 2MB to 2’000’000 solves the issue under the [request] section. Is this a known bug?
