Android 11 wifi adb error "Unable to start pairing client"

Question

I downloaded the latest platform-tools for windows, then I enabled developer mode on my phone and turned on adb over wifi. However after I enter the command adb pair ipaddr:port I get the error "Failed: Unable to start pairing client" (after entering the code).

adb is working fine over the cable, and wifi adb is working with my watch. Any ideas?

Answer 1

I tried all possible way. Then I click on forget wifi and then again connect to wifi then entered the pair and code again then it starts working

Answer 2

Had the same problem. Turns out the port used for adb pairing changes each time you ask for a pairing code. I didn't update mine, so it didn't work. When I realized that, and typed in the pairing code, everything worked as expected.

Answer 3

In my case I was connected to a VPN on my workstation and that's why I got this message. Disconnecting from the VPN fixed it.
