I need more information for reproducing this error. Calling MarketSymbolDownloader.GetMarketSymbolsFile(...) works fine for me.

@license786, If the ssl issue still persists, Please try this answer and let us know the results. https://stackoverflow.com/a/48930280

Regarding the problem with ZipFile, @mathpaquette, we'll need to add nuget reference to System.Compression because it has issues in NET45 (only to this framework). See: https://stackoverflow.com/a/48431402

@Nucs the weird thing about the compression, @license786 targeting 4.6.1.... on my side it runs flawlessly

license786 commented 6 years ago

What is the solution, i should try for now.

I tried both: ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12; and ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;

@Nucs on his computer, I had to uninstall the IQFeed.Client change the target to NET4.5 reinstall to fix the issue.
