Hi,
got the same random issue of SSL error on our API calls (from our front end), got a 495 response status.
It looks like it completely happen randomly.
Referencing another issue that looks like a part of the problem you have (and still not resolved) : SSL Error 495 with Cloudflare & Heroku
I opened an issue at Heroku, they did not find anything yet, a hint could be the “Not trusted” of ssl certificate, but because it randomly happens, I doubt this is the problem.
(myapp.tech does not exists, I cannot provide here our website).
