Hi,

I am repeatedly getting the following exceptions and am stuck here like forever.

Hope someone can tell me what's wrong with my tomcat server  version: 8.5.24 
with Eclipse

Tks.


Did you configure an access log for your Tomcat ?
If yes, can you look into it for the an access that would happen at the same time as the error you show above ?

I am curious, rather than definitive here.
But the word "connect" looks suspiciously like the HTTP CONNECT method (see : https://en.wikipedia.org/wiki/HTTP_tunnel), and maybe someone is just trying to use your Tomcat server as a proxy to something. If so, then someone or something is trying to hack your server, and your server is (correctly) rejecting that call.

Hi,

I am now getting the above error.
There is no further error stacktrace from error log or
console etc.

So far, I have deleted the server and
created new instances but still getting the same error.

I have read the following solutions but
they are not helpful

Please help.

Tks,
Karen
