Synology - Stopped working from yesterday to today.
All of the sudden the API stopped connecting to TMDB. It was working perfectly (sort of) until the middle of the night.
Then it stopped connecting altogether. When I try doing the API test with my API_KEY, it works flawlessly from my browser.
I have the correct ports forwarded on my router. Nothing has changed on my network, not even my public IP. It just stopped working.
I can probably even narrow down the time. Between 2am and 6:30am EST.
I've updated my Synology to the newest update. I restarted the service, reindexed (that didn't help, it actually hurt).
The API was not perfect. It wouldn't auto-load the info into the files like it used to with the TVDB.
I was still willing to go in load the data from the search portion. Semi-manual process I guess...
If there is anything anyone can assist to help me fix it, I would appreciate it.

Since you did the test using your browser and it went well, then it shouldn't be a problem specific to your country or your ISP.
It could be a temporary access issue specific to your region.
In these cases, it usually resolves within 24 or 48 hours.
If it's another type of problem, it might help you to read the data below.

Some Synology NAS/DS Video users have appeared reporting problems.
One of them said there was an update from Synology.
We don't know yet but it looks like this update came with this issue.
So I suggest getting help from Synology's website.

See if any of these threads can help solve your problem.

the user got some responses from Synology.

Travis Bell reported the ports used by the servers

Hi @USER, there's only 2 ports that can be used to communicate with TMDB's service.
These are your standard HTTP 80 and HTTPS 443 ports.

If your problem is not similar to any of the above cases, I suggest contacting Synology Support.
