"Everything is working amazing now. I'm already impressed with the true-tick feed of IQFeed and it's ability to support my 480 symbol layout." - Comment from Tyler via Email
"I just wanted to tell you what a fine job you have been doing. While *******, from what I hear, has been down and out, off and on, IQ feed has held like a champ this week." - Comment from Shirin
"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum
"I've been using Neoticker RT with IQFeed for two months, and I'm very happy with both of the products (I've had IQFeed for two years with very few complaints). The service from both companies is exceptional." - Comment from Public Forum
"For anyone considering using DTN.IQ for a data feed, my experience with the quality of data and the tech support has been very positive." - Comment from Public Forum
"This is an excellent value, the system is generous (allowing for 500 stocks) and stable (and really is tick-by-tick), and the support is fantastic." - Comment from Shirin via Email
"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim
"I am a hedge fund manager here. It’s funny, I have a Bloomberg terminal and a Bridge feed, but I still like having my DTN feed!" - Comment from Feras
"Thank God for your Data Feed as the only Zippers I see are on my pants (LOL), and no more 200 pip spikes to mess up charts." - Comment from Spiro via Email

IQFeed API Questions » HTTP 1.1/ 400 Bad request response upon request May 24, 2022 02:10 PM (Total replies: 3)

I am supporting application using iqfeed, establishing 3 socket connections: Admin, Level1, Lookup.
It works on most of the workstations. However for the one specific workstation I am receiving the following bad request response on Lookup socket:

Normal:
-> S,SET PROTOCOL,5.2
<- S,CURRENT PROTOCOL,5.2

Exception:
-> S,SET PROTOCOL,5.2
<- HTTP/1.1 400
Server: WebSocket++/0.8.2

Actual software installed 6.1.0.20
Any ideas how should I troubleshot this issue?

fwiw, on that specific workstation IQFeed own sample application doesn't show Option Chains.
Thank you.
