Urgent: ERR_SSL_PROTOCOL_ERROR for some users onlyq

Hi,

I’m running a Node/Express API on the DigitalOcean App platform. Some of my users are reporting an ERRSSLPROTOCOL_ERROR when trying to connect and as a result can not use the service at all. I am having trouble debugging this, since only some users seem to experience this issue.

I’m assuming the SSL certs for the DO Apps are all managed, so no need or ability to configure anything custom there.

Hi @marvinCoral,

Usually, the SSL certificate is automatically issued by DigitalOcean and the App Platform.

Having said that, if some users are reporting the error and not all, this leads me to believe there is a DNS issue. Check your records, maybe you forgot a CNAME record there or something like that which is causing the issues.

    I had a subdomain added which I actually didn’t use (just used the APP url directly in my front-end to connect to the API) and might have been misconfigured (I never got the subdomain to work). I removed it yesterday and the reports from users seem to have stopped. Seems like this was most likely the root cause. Thank you!!
