Thanks for taking the time, giganerd. I really appreciate it! The "redacted" config file I posted above contained the IPs of multiple servers for each city the provider has servers in. And each server also had three ports to choose from.
So then I generated config files for each single server, but each of these config files still had three "remote" directives, one for each port. Eddie still wouldn't accept it.
Then I removed all but one "remote" directive with one single port, and suddenly Eddie accepted the config file
The only other thing I had to do was enter the credentials under the "Authentication" tab inside the settings.
Now it seems to be working without any issue. At least so far. Again, thank you so much for your input, giganerd!
