Seeing that Synology released firmware for its router line reminded me to update my router's firmware today. Shortly after the update I began to have connection issues with my PCs. I checked the AGH traffic logs, and they were odd. Nothing appeared blocked or passed. Figuring that AGH was at fault, I changed my DNS to Google, and had access to the world. After grumbling over AGH, I decided to shut down its docker container. But... I couldn't log into the NAS unless I used its local IP. Hmm... (have you figured it out the issue yet? I didn't). So I shut down the container, but the NAS DDNS domain was unusable...
Later... I discovered that the firmware upgrade caused a WAN IP change ... and apparently, the AGH docker container was quite unhappy with that outcome, as the NAS DDNS updater hadn't promptly updated (I'm unsure how frequently it checks, but it seemed to be around 90 minutes).
After refreshing the DDNS domains IP, I restarted the AGH container... and the preliminary results indicate that all is back again. It's still not clear to me why AGH is dependent upon my DDNS domain, but it appears so.
Any thoughts on this? For 2 hours I ran about in circles trying to determine whether the firmware update hosed me, or whether AGH was acting up, or my Ethernet card had gone bust. What a great day!
