Our site does not work with Page Speed Insights and gives the error in the Subject. However, there is nothing wrong with the page. The url is https://www.lifechurchstlouis.org.

Looks like you have a few errors you need to take care of:
https://validator.w3.org/nu/?showsource=yes&showimagereport=yes&useragent=Validator.nu%2FLV+http%3A%2F%2Fvalidator.w3.org%2Fservices&acceptlanguage=&doc=https%3A%2F%2Fwww.lifechurchstlouis.org%2F

Just for fun, I tried running your page on https://testmysite.thinkwithgoogle.com/ -- but it stalled out there as well (stuck at 70%).

In the meanwhile, webpagetest.org is another useful tool for improving your page performance.

Good luck!

You webpage doesn't response complete gzip content:

Try this command curl -H "Accept-Encoding: gzip"  https://www.lifechurchstlouis.org/ | gunzip 

and you will get error: gzip: stdin: unexpected end of file, indicating you're missing last bytes.
