Google Search Console "Change of Address" - Failed Redirection Test

[kernmedia]

I have a client who has a lot of domain variations, which have all been set up in Google Search Console. I requested that the client use the COA feature in GSC for the domains that are now redirecting to other domains that they own (which are set up in GSC).

The problem is that we're not redirecting the homepages to the homepages of the destination domains. So, GSC is giving us this error message:

fails redirection test: The old site redirects to www.domain.com/blog,

which does not correspond to the new site you chose.

Is our only way to use GSC COA for these domains to change the homepage redirect to go to the homepage of the destination domain? We don't really want that since the domain we're redirecting is a "blog.domain1.com" subdomain and we want to redirect it to "domain2.com/blog".

Any help appreciated!

Thanks,
Dan
