Break in compatibility between 5.6.1 and 5.6.2?

[ves011]

My site stop working few days back for unknown reasons, after more than 1 year.
I'm using mosquitto broker and apache as websocket proxy.
After checks and checks i found if using 5.6.1 its working fine, but with latest (5.6.2) it doesnt.
Attached are some logs collected for failure case.

Could be due to: #1874

Try with 5.7.0

replacing "https://unpkg.com/mqtt@5.6.1/dist/mqtt.min.js" with "https://unpkg.com/mqtt/dist/mqtt.min.js" (which should go to latest) it works!

THANKS!
