I wonder if utls fingerprint masking has been unmasked

On some sites, when I use uTLS to imitate browsers like Chrome and Firefox, I get the following error:

ReadVersion: expected 'H', got '\x00' at position 0 when receiving a response.

However, when I use Go's native TLS, I do not encounter this error. So, I wonder if uTLS's fingerprint has been detected and blocked.

Can you tell us which site or at least which cdn is catching it?

Do the fingerprints match when you go to tls.browserleaks.com ?

Which urls exactly? Because that Looks like more a potential bug in implementation than a detection
