Endless transfer of save files (Stellaris)

Hello. The situation is this: A friend with all DLC created the game and we played a small party of 4 people 120 game years. Then we went to bed. The next day, I ran into a save download problem. Once the host has approved the connection to the server, I start endlessly transferring save files.

The funny thing is, if I'm a host, everyone's fine.
I put the game on the way, checked the cache, put the VPN - everything is useless. Maybe someone has come across something like this?
