Thanks YanAvery - simple and clear instructions to follow. However, how long would you expect the process to take. I've copied a snippet from the browser window. It just seems to stay like that and does not refresh / update with any result to say the cert is generated. If I close the window and try the rest of the steps the issue is still there. Any ideas? Thanks.

and I notice when I look at the existing Cert via Network Security Settings > SSL/TLS > Certificate, then Self-signed Certificate and click the "Confirm" button, I see:

Validity

Not Before: Feb 9 02:16:57 2023 GMT

Not After : Feb 6 02:16:57 2033 GMT

So it seems like it is valid? But I still have the encryption credentials expired error printing from any app on my MacBook Air (M1) or my Mac mini (intel)

Why do you say this cert is valid? Unless you are in a timezone that has already reached Feb 9, 2023, this cert is not yet valid. It will be valid starting tomorrow though ... At the time of this writing, it is currently Feb 8, 2023 8:48am EST. This certificate will be valid from Feb 9, 2023 all the way up to Feb 6, 2033 ... So either you are patient and wait until tomorrow or re-generate a new certificate that's valid as early as today.

Thanks - I do indeed live in the future - I'm in NZ which is GMT+13 at the moment (we're in summer time here) so timing was right. Regardless, I *think* the printer thought it was somewhere else as it does print now. Thank you. Your simple method worked - I'll make a note to adjust that printer timezone sometime in the next 10 years! :)
