it looks like the proxy problem when solving via V2 it gives a quite good result, then I switch to (call) v3 Api CM turns into..."proxy time out" all the time.
We are kindly asking you to make bug report in latest version 2.10.8.6.
Please enable extended log in program settings and restart CapMonster.
Repeat the problem recognizing ReCaptcha2 and run Diagnostic.
