website Bugs and error

Hello: Kindly read point by point! The project is When I am use the Googlebot simulator ([login to view URL]), and checking my website ([login to view URL]) then I see errors and it looks like bot did not see my website content. In Chrome I got Error Code: 92; and Error Text: HTTP/2 stream 0 was not closed cleanly: PROTOCOL_ERROR (err 1). With the Mozilla there is Error Code: 52; and Error Text: Empty reply from server. I need help with these issues, preferably for me to have detailed instructions and I'll do it myself. At the moment I even not sure if it is because of some server settings or errors in the header (my website is WordPress based). For assurance Again I am telling that The [login to view URL] tool displays errors 52 and 92 on my website and does not read the page content, nor the [login to view URL] file or sitemap.xml. I'm not talking about the webmaster tool from Google, but a specific app. The task is considered completed only when exactly this app shows the result without errors. Please read the entire request: I want to be sure that we understand each other 100%: 1. Google bot does not see my site well and when I am checking with different tools, it shows 2 errors - 52 and 92. As a result of your work, I want to see on the same tool an absolute absence of these and any other errors! 2. The site is made in the Word Press, but it has a lot of customization, in this regard, after some updates to the WP, the site does not work. As a result of your work, I want to see the excellent work of the site and the ability to update the WP, database and plugins without the risk that the site will die. 3. Some tools such as BruceClay show that Google sees cloaking attempts on my website. As a result of your work, I want to see the absence of such statements. 4. If you can do something else to improve the work and rank the site, I will be further grateful, but for accepting the work, everything specified in paragraphs 1, 2 and 3 must be fulfilled and excuses are not accepted in any way. Price is 30$ and time is 1 day. thanks
