SncRedisBundle: [v2.1.3] Unable to connect to Redis Resource in Azure

Yeah I know, it’s one of those classic “oh DUH” moments that I’m not sure we can do anything to alleviate. Best thing I could think of indeed was doing the Symfony DX thing and extend the access denied exception with some remarks about this. Theoretically we could even only do it when auth is denied and urldecode($pass) !== $pass.

Has been there since 2016 actually 😉

If anyone should stumble upon this issue… I sure hope this will help someone save time.

I had the same problem today and I was going nuts. Then, I used the secondary key just to be sure I tried everything, and it worked! It was a freakishly dumb error: the password (key) is run through urldecode() by SncRedis and my primary password has a + sign in it, which is converted to space and Azure Redis said NOAUTH Authentication required. The secondary password has no + sign in it.
