"we could not verify the certificate: reason = untrusted" when trying to access NCP Activation Page

I have an Odroid HC-1 that was running NCP v1.54.2, it somehow got corrupted. I’m trying to get it up and running again so I tried the last image I could find for the HC2 (NextCloudPi_OdroidHC2_07-24-22.img) and it seems to have gone ok. But when I try to access the activation page either via the IP address or nextcloudpi.local all I get in the browser page is this message “we could not verify the certificate: reason = untrusted”. No way to bypass this or anything.
Any help would be greatly appreciated.

Thanks,
Robert

I managed to get past it by using an Incognito browser window.
