Redis [BUG] log warning: Cannot assign requested address

Describe the bug

First, I don't know if this is a bug or simply a configuration pronblem.

My redis.log file has numerous occurrences of the same warning:

Warning: Could not create server TCP listening socket ::1:6379: bind: Cannot assign requested address

To reproduce

Start or re-start redis.service.
Note the warning in your redis logfile.

Expected behavior

I do not expect this warning to occur.

Additional information

OS: Arch Linux 5.11.15.arch1-2 Redis: 6.2.2-1 PHP-Redis 5.3.4-1

Please let me know if I can provide any other information helpful to troubleshoot this problem.

Thank you,

Your bind config option specifies that redis should bind to both ipv4 and ipv6, but ipv6 failed to bind, and redis continues (binding only to ipv4). If you want to remove the warning, edit your bind config

Just a note, on redis-server 7, this initial warning lead to redis not to start at all.
Maybe more verbose or detailed message (like above) in the log would be useful. Thanks.
