I am having the same error here since this morning; Google says “Submitted URL seems to be a Soft 404” for the https://www.vesio.uk/404 page…
Another problem in the search console that I am recently getting (24th of Jan) is that Google is claiming to see pages from a webflow collection that were deleted over a year ago linked from pages within the website that definitely do not contain those URLs. One of the pages is the sitemap that when opened has no trace of the old collection URL.
Thanks for all the links. I’ve been trying to read up to see what’s the issue and I also came across the same Google Answers Link and Moz link.
My DNS and URL settings are all fine. I don’t have anything fancy going on with them.
The issue/solution I’m finding has something to do with a Header Response. Is this simply just making sure the Meta Title is correct? Or should there be a specific code on that page? I’m not sure. Currently testing the Meta Title and waiting for the webmaster to diagnose if that fix works.
@horia_co As I’ve stating above, the (hopeful) fix for the soft 404. Will report back when I have an update. And for your other issue, are the collection items deleted or archived?
