My Pi-hole (Raspberry) works fine since more then one year.
Yesterday we had a power outage (3 hours), but since them the pi-hole did not work correctly.
It's up and look generally fine, but it looks like it cannot access the DNS resolvers in the internet (possibly also NTP).
Ex. if I start "Update Gravity" got following problem:
##################
[i] Target: https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts
[✗] Status: Connection Refused
[✗] List download failed: using previously cached list
[✓] Parsed 131355 exact domains and 0 ABP-style domains (ignored 1 non-domain entries)
Sample of non-domain entries:
- "0.0.0.0"
###################
Ex. If I try nslookup from console got "SERVFAIL", but the ip of google.com is reachable via ping.
###################
pi@raspberrypi:~ $ nslookup google.com
Server: 127.0.0.1
Address: 127.0.0.1#53
** server can't find google.com: SERVFAIL
pi@raspberrypi:~ $ ping 142.251.37.14

Also cannot upload the debug:

[?] Would you like to upload the log? [y/N] y
* Using curl for transmission.

[✗] There was an error uploading your debug log.

ANY idea how to solve?
(I'm a stupid user and do not have much knowledge with linux)
Thank you in advance!
