Has anybody experienced an issue where SWAG (formerly "LetsEncrypt") will inexplicably stop resolving the secure connection when using duckdns? I've been setting up Bitwarden using SWAG as my reverse proxy. I've properly forwarded my ports and I'm confident that I've correctly configured SWAG, BitWarden, and the necessary .conf files. I will check the SWAG log and it will say "Server Ready" for all of my duckdn subdomains. Life is good. I can access BW from my internal computers, my phone, and my work computer.
Then, things will just stop working... I can no longer access BW using the duckdns link. The log file will start saying "Certificate Not Found, etc". Nothing has changed in my config... I'll restart my router, the NAS, and restart the SWAG docker a few times. Then - just as I'm pulling my hair out - I'll go for a run or walk the dog and come back to find that everything is working again.
Is duckdns not reliable? Is anybody else experience this issue?
