RDP Connection closes

Dear All, 

I have an strange situation... 

Several users reports the RDP session closes with no reason... 

I have checked almost everything....but there seems to be everything right. 

The installation is a stock tomcat8 (in debian 9) with openjdk version "1.8.0_242" for the client. 

And guacd 1.2.0 (first I tried with the docker image, and I switched to a self compiled version in baremetal. 

Both running debian 9 under VMware. 

When I ask to the user what was she doing she explain is using superputty under RDP. And viewing some logs. 

If she does the same with standard putty it works as expected. 
In catalina logs: 

08:23:37.716 [Thread-59] ERROR o.a.g.w.GuacamoleWebSocketTunnelEndpoint - Connection to guacd terminated abnormally: Connection to guacd timed out. 

In daemon.log: 

Jul 23 08:20:55 baselink-be01 guacd[624]: Connection ID is "$85b0a10e-55cb-48f5-b826-2824ae77ae5a" 
Jul 23 13:11:42 baselink-be01 guacd[624]: Connection "$85b0a10e-55cb-48f5-b826-2824ae77ae5a" removed. 

Any help will be appreciated. 

Thanks, 
Saxa

Hi Saxa, 

If the openssl version is 1.1.x on your client side then try these steps. 

edit your openssl.cnf file. 

You need to add this to the beginning of your openssl.cnf file: 
openssl_conf = default_conf 


And then this to the end: [ default_conf ] 
ssl_conf = ssl_sect 
[ssl_sect] 
system_default = ssl_default_sect 
[ssl_default_sect] 
MinProtocol = TLSv1.2 
CipherString = DEFAULT:@SECLEVEL=1 

close and save file. 

Reboot your client and test. 
You can also try CipherString = DEFAULT:@SECLEVEL=0 in config file .
