I signed up on ngrok website and tried to set authtoken with the command
ngrok -authtoken token 4000
and got following error
Server failed to allocate tunnel: Invalid authtoken 'token'.
This looks like an ngrok 2.0 authtoken, but you're using ngrok v1.
Download ngrok 2.0 from https://ngrok.com/download
Then I downloaded ngrok for linux-32 bit, as I am using Linux Mint 17.1 32 bit. But still getting the same error. And my ngrok version is 1.6.
Can anybody help with what should be done in order to start ngrok server in this situation.
Thanks in advance.
