Connectivity test throws Error "No valid ICE candidates were found to establish a peer connection" on slow bandwidth

[iamirfanali]

With latest version 11.0.4 we are getting ICE servers error on slow bandwidth e.g 100kbps to 400kbps and also getting the stats object as empty. Also the bandwidth estimate values are not consistent during various tests performed.

Here are some tests I have performed with various bandwidths

100kbps Up/Down

Error: No valid ICE candidates were found to establish a peer connection

Empty stats object

200kbps Up and 150kbps Down

Error: No valid ICE candidates were found to establish a peer connection

Empty stats object

300kbps Up/Down

Error: No valid ICE candidates were found to establish a peer connection

Empty stats object

400kbps Up/Down

Error: No valid ICE candidates were found to establish a peer connection

Empty stats object

500kbps Up/Down
