Problem with google console - anyone advise?

Hi, my website is around 10 years old, transfered from html to wp, so added a 301 redirect plugin to redirect the traffic from html pages to wp.
I am now getting in the Google webmaster console the following error as in the screen shot.

Page indexing > Page with redirect
These pages aren't indexed or served on Google

When I click see details, I am taken to a a page that has wp and hmtl pages.
Says 219 pending and 2 failed. The failed are 1 html page that redirects to contact us page and 1 WP that works fine.
Validation failed
Started: 11/26/23
Failed: 11/28/23
Sitemap: All known pages

Any ideas how I can fix this?

did you check whether the 301 is set up properly and that the contact page exists and that you've used the correct URL in the redirection?

Additionally, you can test both pages with the "inspect URL" function and see which (if any) issue google detects that prevents the validation...

And last but not least, if all of those 219 pending URLs fail validation too then there might be issues site-wide, so you probably want to wait for the results of the other pages if the failed ones are OK

just have google recrawl under webc onsole,.."re validate" and wait a couple of days
