I cannot reach <a href="https://tryredis.io" rel="nofollow">https://tryredis.io</a> but can reach <a href="https://try.redis.io" rel="nofollow">https://try.redis.io</a> . Not sure if its the same.
@mamato you you are right I made a typo in the url. It should be <a href="https://try.redis.io" rel="nofollow">https://try.redis.io</a><p>Sorry about that. I can't delete this post hence posting this comment.
