Error message on Ebay UK

[Samixbx]

Hi, I have suddenly started receiving the below error when trying to log into PayPal on Ebay UK. I have never had an issue before. Can anyone help? This action isn't supported. Please return and report this error so that we can support it in the future. (invalid client_ID or redirect_uri)

I'm having this error message on the ebay.com all of the sudden too.

Any info about this?

Ok the issue is with the browser.

Namely the latest Vivaldi browser v2.4.1488.38.

The payment went through just fine with Edge.
