Unexpected end of ZLIB input stream


#1

Hi !
Sometimes I have a strange synthetics probe monitor failing : “NetworkError: Unexpected end of ZLIB input stream” :

Few seconds after, the next probe says “Monitor recovered”.
The website monitored is delivered (and gzip compressed) by NGiNX, AWS ALB then CloudFront.

Do you know if this is a bug from New Relic side or my side ?

Thanks !

Would you mind sharing a permalink to this monitor so I can take a closer look? :slight_smile:

Hi @cyril, this seems to be a Network Error occurring somewhere along the line, though I can’t find any more details in our backend as to why. A good place to look would be to track the X-abuse-info header to see what your server responded with when the Monitor contacted it. Let me know if you find anything :slight_smile:
