Before anyone asks, yes, my RD is still active and current 
I’m able to get links in Fen, Crew and Syncler, but for whatever reason, I’m getting “No Playable Sources” in Seren. It was fine a week or two ago, so nothing in my setup has changed. A4kscrapers is current (v2.80.0) and Seren appears to be current, as well (Nixgates 3.0.0). Running Kodi 20.1 on Android box with plenty of space. Cleared caches, etc.
Just wondering if anyone else is having issues?
Make sure your real debrid is up-to-date.
Re authorize your account on the app/apk you are using
Delete your devices in real-debrids website and re add them
Make sure they are added in real debrid.
These steps are a must and will solve the issue 9 out of 10 times. Also check real debrids Twitter for status updates.
Usually, reauthorizing RD within the addon will solve most similar issues.
Seren’s great when it works, but I’ve moved away from it for a good long while now. My current goto is Fen.
Working great here. 
Same here, working fine. Seren i feel has the least amount of issues. Being a premium addon helps.
I have had to re authorize once in awhile but nothing major.
Ready to give up on Seren. However, when I get the Seren error I go to my add-ons section for Seren,then under versions I chose Nixgates version 3.0 (even if it’s already installed). This re-installs Seren and the 4kScrapers. Then reauthorize Real Debrid in the app making sure to hit ok when it’s done.
Probably not doing something right, Seren is one of the best addons out there.
Ok, RD account is still active. I deleted all devices in RD, uninstalled Seren and the Nixgates repo from Kodi, manually re-added it. Re-auth’d my Trakt and RD despite the constant 'Seren error, check log for details" warning. It won’t let me get to installing the A4KScraper package because of the error.
Did you install the provider package…?
No. As I said, it won’t even let me go into Manage Packages to install them because of the constant error
Something in your Kodi settings file is probably messing with it. You can try to pull the error log and spend hours trying to troubleshoot or you can download a fork of Kodi and do your installation of Seren on that to see if it works. If it does work then you’ve got a choice. You can keep it like that and open the fork when you want to use Seren, or you can completely uninstall Kodi and start over. You can make a backup before uninstalling if you want, but if you do a restore you’ll probably still have the same errors.
