Hi all!
The problem has finally been solved. I would like to thank every one for your effort and contributions. I could not have solved the problem without your help!
After the laborations with curl, I felt that the problem must be connected to the ciphering. I knew that the only way it worked with curl was when I set the -2 option forcing it to use SSL ver 2. Therefore I today read some more about the cihpering in LWP and tried to set SSL ver 2 also in LWP ($ENV{HTTPS_VERSION} = '2') and tada, it finally worked :-) Actually, I already tried this option yesterday, but then I ran through the recently installed proxy and that probably screwed thing up somehow.

Hope this thread can help others with same problem. I have certainly learned a lot while struggling with this.

Best regards
/Johan
