Galene not connecting outside lan

I was looking at a previous post and it mentions using synapse as a turn server for galene. I don’t have synapse installed on my principle domain xxxx.domain.tld.

I also do not have it installed on my galene subdomain - galene.xxxx.domain.tld. I also noted an issue with installing let’sencrypt after the galene installed rather than before.

Could these be the issues with accessing the server outside the lan?

Thanks
