NextDNS 1.10.1 Stops working on Raspberry Pi's

I have 2 Raspberry Pi's that I have NextDNS installed on for DNS on my network.    They have been rock solid for almost a year.   Last week, I updated NextDNS to the latest version on Github, 1.10.1, and now, after like <24hrs of use, NextDNS resolution completely stops working.   The Pi's are fine, I can logon to them but if I do a digg for any name, it times out.     I reboot the PI's, NextDNS comes back, but slowly stops working within a day.   Is there a way to go back to a prior version, or has anyone seen this before?

    What do you get in the logs when it is failing?

      Olivier Poitrey What logs specifically would I look at? If I run top on my pi's when its happening, nextdns is using almost all of the CPU. If restart it, the cpu usage drops to nothing, but then slowly starts creeping back up way high. This is on both a Pi3 and Pi4. I have another post where the same thing is happening on 2 different Synology systems. https://help.nextdns.io/t/m1hzmq8/synology-nextdns-pegging-cpu

    I'll have to wait for it to fail again and check, it seems to be load based.   If I just point one client to it, it doesn't slow down or stop, at least that I have noticed.  But if I point all my clients (around 75-80) to it, within 24hrs it will stop.   I'll see if I can get the logs.

      Andy what is the output of “nextdns config”? I’m looking for “nextdns log” output when it is failing.
