JetPack Connection Error

Hello, may I ask for some help with my JetPack? I’m sorry in advance for writing so long.

TLDR: I sometimes get the “Couldn’t resolve?host” error and sometimes don’t. I am still able to connect to JetPack, but the connection keeps reappearing and disappearing. Is that normal for the “Couldn’t resolve host” error? Or should I be unable to connect to JetPack at all from the error? As for the error, should I wait for 72hr to see whether the error still appears later because I have recently changed my DNS Name Server?

-_-_-_-

My JetPack is somewhat wacky. The connection is quite unstable, one minute I got the “Elysian Pit is not connected: 200” in my Site Health, then one minute it disappear a.ka All is Fine, but then another minute and the “Elysian Pit is not connected: 200” appeared again.

I have tried reinstalling the plugin, and, the reinstallation process is also wacky. One time I will get “The JetPack server was unable to communicate with your site [IXR -32300: transport error: http_request_failed curl error 6: Could not resolve host]”, and after waiting for some minutes, I will be able to connect it again, but after some time, the error “Elysian Pit is not connected: 200” will appear again.

I got to connect it to my website, eventually, but all the features connected to the JetPack got connected and disconnected (i.e, the Stats, the Comment, etc). The issue also appears on my connected WordPress.com Account, one minute it will be fine, and another minute a glaring red (!) with the description “This Site cannot be Accesed” will appear on My Dashboard.

I have checked the Fixing Connection Issues. The xmlrpc.php showed what to be expected, wp?config.php and .htaccess also work just fine. No plugin disables PHP?XML. I also checked the Jetpack Debug Tool, but it only showed “An unknown error has occurred.”

The most similar case is “Couldn’t resolve host”, and I indeed changed my DNS Name Server to Cloudflare yesterday. But, this error also appears when my DNS Name Server is still the default BlueHost Nameserver. The DNS Name Server in whois.domaintools.com already showed the Cloudflare Name Server.

But, I’m honestly not sure whether 1) the “Couldn’t resolve host” error will let me connect to JetPack so it is normal and I only need to wait up until 72hr and see if the issue still persists or 2) it’s another issue entirely.

I have contacted my hosting support and they said I should ask here.

I would be grateful for the help, very sorry for the long text.
