Yes -- these are indeed annoying! A 404 error is an HTTP status code that means that the page you were trying to reach on a website couldn't be found on their server.

To be clear, the error indicates that while the server itself is reachable, the specific page showing the error is not.

Re-read the last sentence... noting the word, "specific".

A site which tells all about it -- may perhaps, worthy of a read by you -- is at:

Believe it all relates to original post executed with Tap-Talk …. And I’m not a user of it

Can’t really help with a general question such as you have presented.

What page(s) are you trying to open, does it happen often, are you attempting to view deleted photos, what web browser are you using, are you using a computer or phone, if a phone or other device then I need all the details about that such as android, apple or home made, what operating system is on that device and with what updates…..

It’s not as easy as one general question.

How about let’s start with restarting your device and work from there.

I think No_1 is on the right track. Works for me.
