Hi Sadaf, This is similar to an already fixed bug #82 Can you post your configuration? (uRaiden changeset and pip freeze output should be enough)

Ha, it seems you are using Infura - we haven't really tested uRaiden with this backend. There's an open PR #320 that adds support for it, but so far it still needs more testing. Infura seems to not return events reliably and thus uRaiden sometimes fails to register open channel.
