Invalid URI in request amobee-1

[yaashul]

I am getting this error in my error logs. Strange this is this ip doesn't access any page of my site just this entry in error_log file.

Are you on shared hosting?

Some shared hosts are these days, NOT providing error logs for specific domains, rather error logs for their entire server and/or customers.
This pretty much makes error logs useless as a tool.

No it is a dedicated server. only 1 domain logs.

Then, compare these error log entries to your actual raw logs for date & time.

You mean the offending actions show up only in error logs, not in access logs? Can I assume you haven't done any conditional logging (where some types of request are intentionally excluded from logs)? If so, error-but-not-access points to an internal request.

Can you find anything relevant in access logs for roughly the same time and IP? Access logs can sometimes get quite hiccupy, with requests ending up several seconds out of alignment in logs.
