@fabiobc - I'm getting the same OAuth redirect_uri error starting today on an existing Jira connection. Looks like this is broken on Retool's side and affecting at least 2 services so far.
On a separate thread for the Jira version of this issue, a Retool person said she was looking into it w/ their on call team. You might want to follow that thread, too, to see if there's a quick resolution. (@Tess FYI above -- same exact issue I saw w/ Jira.)
