Your location shouldn’t be an issue, I personally don’t recommend logging in on 1.13.2 simply because I prefer 1.12.2, but I do know some players have had issues logging into 1.13.2 in the past, have you tried logging into the server with 1.12.2 or a lower version? If that does not work, please make sure you have no additional unallowed addons or mods other than Optifine and Labymod. If that still doesn’t work, maybe send a screenshot of the error it’s giving you or make a ticket on the website or Discord.
