DKIM not verifying again.

DKIM not verifying again.

I've had my SPF and DKIM records setup correctly with my DNS (Namecheap) for darklingdesigns.com for quite a while now and all has been working fine. Now I suddenly have warnings that DKIM and SPF are not configured correctly again. I used the SPF check tool in your help article and that IS show correctly. Now my dashboard is also showing the SPF correctly again. It's been several days on the DKIM though and I still can't verify. I tried generating a new code and still nothing. The DKIMCore check does not seem to work on any browser for any website I've tried it on. It's just endlessly says connecting. I've got a few other website configured virtually identically except for the actual code and they are showing verified and working. Any ideas where the problem lies?

Edit: I've changed my nameservers over to Cloudflare like my other sites which are having no issues. Same problem is still persisting. DKIMCore is working and shows the key as valid, however it times out when actually trying to check for the published key and it telling me there is no public key. It does this on every single website I manage though, including all the ones that are verified as working. So I don't know if it can be trusted.
