Synology Install with SSL Randomly Looses Connection

Just installed HA by following mariushosting tutorials. I installed it on my Synology NAS via Docker using the DDNS and certificate. I have a wildcard certicate setup in reverse proxy. Everything works great for a couple minutes when I connect via my subdomain. After a few minutes I get page can’t be reached DNS_PROBE_FINISHED_NXDOMAIN. It will randomly start working again on it’s own, then fail again.

Any ideas what’s going on here?

I reinstalled home assistant with supervisor and set it up with duckdns addon instead. It now works fine. I did more testing, but never came up with a reason for it working intermittently.
