Random Error when querying the web server

Hi,

I came across the below error which is quite infrequent and sporadic when I query the web server. Not sure why this occurs.

JavaScript

[TSTSERVER1] ***In 1 presentation contexts

[TSTSERVER1] ***#Possible transfer syntaxes: 1

[TSTSERVER1] ***No accepted presentation contexts/transfer syntax found in 1 candidates

Could you please guide me on how to debug this? Not familiar with Lua. Thanks.

Hi,

I am not sure why this happens and have not seen this before. The lua script in line 11 calls a dicomget that fails with the message in line 1. I guess it works on the next attempt? What OS are you using?

Hi Marcel,

I am using Windows. Yes, you are correct. The next attempts work fine. But it does occur once in a while and I have no clue why!
