Sharing on LinkedIn doesn't work / Problem with LinkedIn Page Inspector

We run a website from where users can share pages on LinkedIn using the basic sharing URL https://www.linkedin.com/cws/share?url=https://THE_URL.
This worked without any problems for years, yet recently we are facing problems that we cannot explain. Some of our URLs can be shared, while others, pointing to very similar pages, fail.
All of our sharable pages are served from the same infrastructure, same servers, same setup, same TLS certificate, rendered from the same application, etc.
As an example, I attached screenshots for two pages, which are basically identical, except from a few very small details.
While https://open.sap.com/courses/fg1 can be shared,
Screenshot: A "Create a Post" widget on LinkedIn with correct page preview
the almost identical page https://open.sap.com/courses/fg1-1 can not be shared, the sharing widget shows an error:
Screenshot: A "Create a Post" widget on LinkedIn with error message in preview area
Additionally: since a while, both pages - fg1 as well as fg1-1 - cannot be opened in the LinkedIn Post Inspector - this worked earlier, there was no notable change on our side.
The error message in the post inspector says (for the page where actual sharing in the widget works):
Ingestion Feedback
Error We encountered a server error while trying to inspect the URL.
URL redirect trail
1 0 undefined https://open.sap.com/courses/fg1
Summarizing: I am quite confident that this is not an issue caused by our infrastructure or the application - otherwise I would expect that all pages resulted in the same error when sharing.
Does anyone else face this issue or did so in the past and found a solution?
Note: it feels a bit odd to post this question here instead of filing a support ticket, but I was told that this would be the way to reach out.

LinkedIn Autofill button not showing

I want to implement the LinkedIn Autofill into my staging website to test the autofill feature into the website form.
I have created LinkedIn Insight tag and implement into my staging website and follow the instruction guide https://www.linkedin.com/help/lms/answer/a424393/linkedin-autofill-setup-guide?lang=en, the autofill button didn't show out.
In the LinkedIn Campaign Manager, Website Tracking page did show the Tag Domain implement successful with my staging domain listed there.
On my staging site, I use chrome inspection tools and the console show the following error message without any further details
Failed to load resource: the server responded with a status of 400 ()
Any suggestion how to implement it?
#linkedin
Please try it in your production instead of staging.
We faced a similar error in our staging site where the Linked in Autofill button didn't show up and a 400 error code for https://www.linkedin.com/autofill/ in the console. The reason was the issues with whitelisting. Though the linked in representative confirmed that our staging site has been whitelisted, it still didn't work. They suggested us to take it to production and check. It was actually working in Production as expected. Please try it in your production instead of staging.
Adding the steps that we followed:
Add linked in Insight Tag to your website. Please follow the steps here
Add the autofill script to the html page where you want the button to be displayed. Note: If you are using a CMS, where this autofill plugin is being added to modules and re-used across your websites, make sure the script is added inside a proper html structure.
Html code snippet
Check if the Insight tag is working properly by opening the network tab and check for the insight tag link. Please refer the link
Whitelist your website domains by contacting the Linked In rep.
If you get a 400 error for https://www.linkedin.com/autofill/ in your staging site, try it in your production url after it has been whitelisted.

Share Facebook Wordpress

I have a big problem. In my WordPress site sharing on Facebook does not work... I tried everything but did not want to work. The open graph inserts them, they are present, but I do not see nulal if I share on Facebook. Attached what the debugger tells me. I do not want it to be a problem of subdomains or SSL. Until recently it was all.
This is response Debugger Facebook: https://ibb.co/f2ykXz3

Site didn't send any data and won't load fast and whole content after some interval

I have a wordpress website. When I try to open my website it takes more time to load. Also when I try to open Admin panel the same problem is arrived and browser shows like "Your site didn't send any data" error with err_empty_response code. Website and admin panel works normally sometime and suddenly the error starts. Is that hosting problem ? Also the whole content of website is not loading.
error screenshot:

Can't access site (or admin) - no error messages

Since a couple of days ago our info site (WP) isn't working at all, which is strange because we haven't done any changes lately whatsoever. No error messages shows up and what happens is that it times out (same with admin interface).
It started with a couple of strange error messages that was connected to a couple of plugins (Google maps ready and YouTube widget responsive) and after disabling them through FTP they dissapeared but instead the site just load and load and then times out.
Because no error message is shown and we're not able to access the admin interface it is very hard to know what's wrong here. Does anyone have any idea what could cause this problem?
The site: inteokej.se/info
what I can see is your site is having redirection loop. inteokej.se/info redirects to www.inteokej.se/info and vise versa. try to resolve that.
