We have multiple servers that communicate with each other. This has worked without issues for years.
A few days ago, a request between the servers failed. The error:
file_get_contents(): Peer certificate CN=*.mytrafficmanagement.com' did not match expected CN=www.my-domain.com'
The error only pops up rarely, a few times per week. All the other requests (which are exactly the same) work fine. We use Plesk for managing the server.
My hosting provider is: OVH
I already did a google search, and found another website having the same issue:
I'm not sure if this is the right place to ask. But I'm a bit confused about this error. Did the request between my servers somehow got redirected to another server with the wrong certificate? I didn't make any DNS changes...
do your server manage mytrafficmanagement.com too? it goes to a parking page so it's unlikely but looks like your server failed to parse or send SAN at tls handshake
I personally don't think this be debugable, but better retry connection. I would not be surprised if it was cosmic ray hitting Lan cable flipping a bit in transaction
Not the best place to ask. Seems more a DNS problem or something odd in php error handling. Might even ask OVH how to check DNS.
To debug you could replace the file_get_contents with php curl_exec. That would allow you to see the response headers and other details possibly. See php programming forum for details (even stackoverflow). Not sure this would help but it might.
