Can't connect to remote server using Remmina

US flag
Frank

I used Remmina for extablishing an RDP connection to a remote server for which I have credentials. I used it until a few months ago and worked smoothly. Today I tried connecting to that same server again and I get the error "Cannot connect to the server" I don't know why I get this error. When I first tried to connect to the server I got no errors so I didn't have to change any setting so I don't know if any setting was mistakenly changed. Anyone knows what I can do for solving this problem?

EDIT: My Ubuntu version is 22.04, the Remmina version is 1.4.25 I turned on debugging mode. This is the log. I'm sorry if I drop the whole log but I really don't know where's the problem. Maybe it is the rco_on_disconnect signal?

I suppose you need another client to test and rule out the possibility that something has changed on the server. Or, maybe whoever looks after the network(s) in between haven't suddenly added a firewall between you and that server.

Great to have you join the community. Can you please add some details about your Ubuntu client (e.g. release)? As well, Remmina also offers a debug option. Output from that would be helpful. I mention that, in part, because Ubuntu clients have (obviously) changed over the years, and Remmina has expectations about connectivity.

@Ray I looked for public RDP servers for checking that aspect but I couldn't find any. Do you know if there exists a public RDP server?

@Frank. Thanks for the debug output. Please review one possible solution here: https://askubuntu.com/a/1419793/32664. This resolved my issue (similar in some respects to your current issue).

@richbl I solved the issue but I don't know how. I tried multiple times to connect and it eventually worked but I didn't make any changes

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
