Hello Ruben, which URL are you using to login?

Are you using this URL? https://rntlab.com/courses/

It’s weird, because in order to comment on the Forum (like you did), it means you’re already logged in.

Regards,
Rui

Hi Rui,
I forgot mention that it happens from Linux (Ubuntu on arm64 and Debian on arm32)
on my iPad where from I’m writing, works I’m  and in a Mac too. It’s weird because all has the same external IP

Sorry yes I’m using https://rntlab.com/courses/ and the link from randomnerdstutorial.com
 

• Which browser are you using? Can you try using a different web browser?
• Did you fail to enter the password too many times in a row?
• Are you using any extension to change your Laptop IP address or block ads?

This website has no ads, but using those plugins might break some of the site’s required functions to work properly.
Thanks!

Chromiun,
Now it’s different ask for a math operation 4 + 6 =   …   then appear wordpress logo saying your user and pass are empty 
It look like a pishing
