RDP connection times out before 2-phase authentication completed

ph flag

We have a connection to a customer site that requires (phone-back) 2-phase authentication.

If I am slow to complete the authentication, Remmina times out with a "Cannot connect to RDP server" error. However, if I'm quick enough (less than about 15 seconds) the connection goes through fine.

Usually, if I re-connect when I get the failure, it goes straight through, as I'm already authenticated.

Wondering if anyone knows where this RDP timeout is defined, and can it be increased?

According to the manuial, this is in the 'Advanced' tab of the RDP connection profile (https://gitlab.com/Remmina/Remmina/-/wikis/Usage/Remmina-debugging)
ph flag
Well, in the version I'm running (1.4.2) there is no timeout value in the Advanced tab, and, if the default is 900ms (as your link states) then it can't be that timeout, as mine times out at about 15 seconds, not 900ms.

The answer is to upgrade to Ubuntu 22.04.

Since posting I upgraded from Ubuntu 20.04 to 22.04 and this problem has gone away.

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.
