I try to run a Python package (script) in a snap. In classic mode it runs normal. Connect to a radio server, get content. In other modes I loose network connections very quickly. Some server with higher ping times do not connect at all. I tested it on several VM’s incl. Bunsen B2, Fedora 29, Suse15, Ubuntu18 +20.
For me, it looks like a problem with the container use a network: use bridged, use host. But I have no idea how this is implemented.
GOOD

I highly appreciate any suggestions on where to get error information, or how to get network error information at all.
