Dorico 5 Pro Not Starting

When i launch Dorico 5 Pro it hangs with the following message

Parsing of online version check failed

How do I fix this?

The messages you see on the splash screen during start-up tell you the last thing that happened (or failed to happen) rather than the thing that Dorico is trying to do right now. Dorico is trying to start the audio engine, and apparently it is unable to do so.

If you restart your computer and then try running Dorico 5, does that help?

Are you on Windows or macOS? What version? What kind of hardware do you have?

Thanks! I think I found the problem. Another application (UA Connect) that was suppose to start and run in the background was failing.

I soon as I uninstalled that application Dorico Pro 5 starts with no problems.
