For some reason, redis connection to my project is failing despite I have all the right variables added. I made the same operation a few days ago, and it worked as expected.

Error: getaddrinfo ENOTFOUND redis.railway.internal
at GetAddrInfoReqWrap.onlookup as oncomplete {
errno: -3***,
code: 'ENOTFOUND',
syscall: 'getaddrinfo',
hostname: 'redis.railway.internal'
}
