You need to have a Filesystem to do OTA. Use the Tool->Flash Size to assign a FS setaside.

Same error here:

Sketch uses 398820 bytes (19%) of program storage space. Maximum is 2093056 bytes.
Global variables use 73356 bytes (27%) of dynamic memory, leaving 188788 bytes for local variables. Maximum is 262144 bytes.

Also running into https://forum.arduino.cc/t/ide-2-0-ota-mdns-discovery-only-intermittently-finds-nodes/1036850/2 , not sure if related.

As for the error, I've checked both the firewall on my router as well as ESET Internet Security on the Arduino IDE W10 host, nothing is being blocked as far as I can tell, but the error makes me think its not a network issue but more a library issue.

edit: Downgrade do 1.8.13 and OTA flash works just fine, both the mDNS detection as well as the flashing itself.
