[Tails-dev] Connecting to TOR

I typed in the following bridges obfs4 194.9.172.33:465 and obfs4
216.229.75.65:35602 and received the message TOR failed to connect. Do I
have to type in the string of letters and numbers that came with the
address? Will I have to connect this way each time I use TAILS? I'm
finding this confusing. Thanks for your help.
