Summary:
Some freinds and me are oftenly playing Factorio together. Therefore one of us hosts the game and the others join. Non dedicated, password protected and max 8 Players. All other settings are untouched. This does not work anymore on 0.14. This is independent on who tries to host the game, detailed description: see next point

Description/settings/symptomes
- Settings work on 0.13.x (checked 3 times now)
- UDP port 34197 is open, to be shure even on TCP (as listed, works on 0.13)
- 2 of the players (wich are mostly the host because of their great internet connection) are in the same local network
- to exlude a error between current version it was tested on 0.14.7, 0.14.6, 0.14.5 and 0.13. only last one was "connectable"
- Server always appears on the Server Browser showing the correct settings but sometimes a player count of 0 (which is impossible since the host is always on it).
- server has no ping
- server shows connection error message before passwort entry (so it's not a wrong passwort entry).
- connection is not influenced by activiated mods
- connection is not influenced by password or set player count
- players always connect through the server browser
- if on 0.13.x the setting of "ping" is set below 150, the server won't be listed in the server browser or the same errors as posted above will appear. Except of the player number issue. The ping setting is missing on 0.14.x so that may be a error cause (is there a new default?).
I know its mostly impossible to reproduce the Error by the given information, but I will try to answer all questions to help finding the issue. Would be nice if someone confirm having the same issues.
Edit: Here the Server Log:
