I'm having trouble with multiplayer. I am hosting a server on a dedicated tower with DynDNS. I am able to connect by running a client on the server machine and my laptop, using but my local address and the DDNS domain. I am able to connect from outside the network with my laptop (tested using mobile hotspot). My friend was having trouble. They kept logging into my server only to be kicked. We kept solving one problem only to find another. (asset mismatch box unchecked, then mods didn't match the server, so I zipped up my whole mod folder and sent it via cloud, then they needed to upgrade their archive utility to correctly unzip) After they got the modpack installed correctly the game refused to load, just gave them an alert window full of code https://imgur.com/a/FPH2i meanwhile Im reading THIS: https://community.playstarbound.com/threads/july-13th-build-unable-to-load-sb-error-message.117569/ however I'm running 1.3.3 stable version.... So my friend's taking a break from trying for now. Next step is to try backing up their save and reinstalling. Figured in the meantime I'd float this out here since the issue doesn't seem very well documented. Maybe someone else has some ideas? EDIT: I Found this: https://community.playstarbound.com/threads/application-threw-exception-during-startup.126163/ looks like our exact issue, trying now.
