问题
I'm launching a RoR application over AWS ECS in a Fargate task. This exact task has been running successfully for over a year and started failing (i.e. can't connect via browser) since about a week.
After contacting tech support, I found that when I use CURL to connect to my site from the command line, it responds quickly with the full HTML document. When I try to use Firefox / Chrome instead, it just times out with either 503 or 504 error.
Has there been some changes to SSL / certificates, or could it maybe be caused by networking issues (IPv4 vs IPv6)? I'm kind of clueless as how this is caused, and what I can do to restore.
Thanks
