Hi,

We promoted application to production, but from time to time (I can say very often) we get a connection error:

"A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 199.255.120.210:443"

Could you explain me why?

Thanks!

I am having the similar issue. Were you able to fix it? could you please share?

We already use password flow:

await rc.Authorize(Username,Extension, Password);

It seems like network issue. Do you have stacktrace? Or which API call throws this exception?

It's hard to say what could be the cause of this problem.

Had this problem happened before when you test it on sandbox? Is the app now running on the same system (browser, OS, internet connection, firewall etc.)

Can you give more details of what type of authentication (password flow or 3-legged authentication), APIs you call from the app etc.
