I get this error when doing webrequest

Hi,
I open my project this morning, it was working fine but all of sudden… I get this error message from the same coroutine

Curl error 51: Cert verify failed: UNITYTLS_X509VERIFY_FLAG_CN_MISMATCH

Can someone help me on this? I tried google but I can’t find the same error message.
Thank you

Same here. Worked with my dev server, but now that I’m hitting an AWS server I get this.

I found this this thread and after wait for few days. it solved on its own.
