I just updated to 5.6.3. Nothing has changed - the problem still exists.

Hello Akash, I recently updated to macOS 10.13.2 and Safari 11.0.2, but nothing changed. I still get the connection error. @Dirk Kolbe I guess like myself you are from Germany, use German keyboard layout and "," as decimal separator? @Akash Vyas Maybe this could be a hint why you can't reproduce it? Also, the German "Umlaute" (ä, ö, ü) often are the cause for strange software problems. I think have used some in the content of the Enpass database, but not in folder paths or user name of my system.

Is there still no reaction at all from the dev team?

Hello Dirk, I have EXACTLY the same configuration and the same problem. Also Chrome works as a work-around. On a different Mac I have OS X 10.11.6 El Capitan, the rest is the same. Here everything works fine. On the 10.13.1-System I used the Migration Assistant from the 10.11.6-System, so most of the preferences should be the same . Stefan
