Description:
after installing in parallel to 8.0.47 CE, and importing the connection profiles from 8.x series, it can connect on any of them

How to repeat:
1) install Workbench 26.7.0
2) import connection from 8.x
3) try to connect
it wait forever with e circle animation

also the button "Test Connection" does nothing

Do you see anything happening with tcpdump/wireshark (best with host=127.0.0.1 so it uses TCP)?

I cannot install Wireshark on company PC as is considered an hacking tool.

About "tcpdump", it is available on Linux, but on Windows isn't.
I checked also in Cygwin and MSYS2 I have installed for SW develop, but there isn't.

Any other suggestion?

Maybe PktMon?

OK, it require admin right so I can do only some little tests.
Our MySQL server is at IP:10.90.0.34

I started and admin PowerShell and typed the following commands:

PS > pktmon filter add -i 10.90.0.34 -t tcp syn
PS > pktmon start -c
=== here I tryed to connect for 30" using Workbench 26.7.0 ===
PS > pktmon stop
PS > pktmon etl2txt D:\PktMon.etl
