Randomly ETIMEDOUT when connecting to MYSQL

I have used Retool for a month and since a week ago, my app started failing because of ETIMEDOUT error when querying data from MySQL. Sometimes it does work, sometimes it times out. See attached screenshot with logs from just Testing the connecting on the MySQL resource page. I thought it could be due to IPs whitelisted, but it's strange that sometimes it works, sometimes it doesn't.

As additional information, I requested access to the Beta version of Multi-pages. This error started happening since I got the Beta access.

We reviewed and added again all white-listed IPs required, and it seems is working now
