I share my problem because I think it can happen to others.
I use Google Cloud. Everything worked well with SSL of Cloudflare & WordPress.
About 10 days ago Google Notice that would open a new VM for our Tier and that we should change it on August 30.
Yesterday my site stopped working, but already warned, after making the change everything seemed to return to normal. When activating the new VM my page opened fast.
However, today in the morning I see that my site is fallen. The problem is not Google Cloud because I can access my site from the original IP address without problems.
In cloudflare I purged the cache, but the site is still fallen. The state of the proxy seems healthy.
I must update some information on my part so that the website works again?.
Or is it normal, I do not have to touch anything and I just have to wait …?
Obviously the change did not like cloudflare. I really need my site to work. There is a lot of work there.
From already thank you very much
