normally, i contact my brother with teamviewer to solve problems
today, on a fresh install of windows 10 on a Dell 790 USFF - it did not work
when i click connect - the pc is not found
However, if my brother contacts me - all is ok
we checked the settings of the Windows Defender - real time and cloud protection are on
what can be the cause? - is suppose it is a setting, since it's the first time
