I’m following the Rails Getting Started Tutorial and I followed it to the end. The only change I made was when I created a new rails app, I designated database=postgresql.
When I visit the app, it takes forever to load, sometimes throwing a 502 error. On the dashboard monitoring page, I’m repeatedly getting Could not proxy HTTP request and /usr/local/lib/ruby/3.1.0/socket.rb:1214:in __connect_nonblock’: Connection refused - connect(2) for 127.0.0.1:6379 (RedisClient::CannotConnectError)` errors. Additionally, sockets don’t seem to be working–when I update a name on the site with another tab open to the /names index page, I don’t see the update on my other tab unless I refresh the page.
WebSockets won’t work until you have redis set up, so let’s fix that.
127.0.0.1 is localhost, which likely indicates that the REDIS_URL secret is not set.
First check to see if you have redis allocated:
fly redis list
If you do NOT see any names listed there, create one with:
fly redis create
Look for a line that looks like Apps in the personal org can connect to at and copy the URL and replace <url> in the following like with that value:
fly secrets set REDIS_URL=<url>
If you DID see a name in the fly redis list command above, you can find the redis url by running the following command, substituting <name> in the following line with that name:
fly redis status <name>
Once you have the URL, run the fly secrets set line above.
