Description

In the version 3.5.0.89, the SMB connection does not work. Adding a new connection to a Fritz!Box 7490 with latest firmware fails.

The logs show, among others, these errors:

[10-24 17:40:56.811 15440:16132 E/SmbComNegotiateResponse]
Signatures are required but the server does not support them

[10-24 17:40:56.813 15440:16131 W/System.err]
jcifs.smb.SmbException: Failed to connect: 0.0.0.0<00>/192.168.77.1
...
[10-24 17:40:56.814 15440:16131 W/System.err]
Caused by: jcifs.util.transport.TransportException: jcifs.smb.SmbException: This client is not compatible with the server.

See full log: logcat_10-24-2020_17-41-04.txt

I had to downgrade to an older version. Version 3.1.2 RC1 (latest in the F-Droid Repo) works without this problem!

Research direction

Start by reproducing the SMB connection failure against a Fritz!Box 7490 using the reported current version, then inspect the attached logcat_10-24-2020_17-41-04.txt and compare it with the working 3.1.2 RC1 behavior. Done means the current version can connect to the reported server without the incompatibility or signature-negotiation errors.
