Launcer Error 75?

[daxter154]

Hello all, im trying to install PR (obviously) but I'm having issues (obviously). i tried to run the manual updater (prbf2_1.0.29.0_to_1.0.30.0_client_patch). but i get an "update failed" error that says:

Error

75: Update failed. unable to connect to verification server. please check your connection and try again.

But my internet is working fine, i opened ports, and looked up other solutions to 1301 errors and tried as many as i could... any ideas?

A firewall or antivirus program is blocking PRLauncher.exe (and possibly also PRBF2.exe)
Some routers come with built in firewall, that also has been know to cause this issue.

What firewall do you use?
What antivirus product?

firewall is off. no antivirus (using a vm)
