How would ElectrumX syncing issues cause you to lose coins?  I presume you configured bitcoin core with --disable-wallet.  I have a similar issue where I have a low number of SSL connections and I cannot connect to my server via my wallet.  Is this a physical home server or a virtual server?  I think my issue is cause by a networking error: bad router config, DNS issues.  Since your symptoms are similar, we may have the same source problem.  I pinged your server domain names, but they did not resolve to an IP address.
