Could not pull content from connection due to error. API endpoint error.

[IonTulbure]

Describe the bug

Distributor stable Version 2.0.4.

I can establish connection from site X to site Y on a Shared Hosting (Hostinger)

However at Pull Content screen i get this error:

Could not pull content from connection due to error. API endpoint error.

---

On both of these 2 websites i get the following error (Query Monitor)

Post: https://site.xyz/wp-json/wp/v2/distributor/list-pull-content  (confidential)
500 Internal Server Error
Caller: 
Distributor\ExternalConnections\WordPressExternalConnection->remote_post()
wp-content/plugins/distributor-stable/includes/classes/ExternalConnections/WordPressExternalConnection.php:243
Distributor\ExternalConnections\WordPressExternalConnection->remote_get()
wp-content/plugins/distributor-stable/includes/classes/ExternalConnections/WordPressExternalConnection.php:176

wp-content/plugins/distributor-stable/includes/pull-ui.php:529
do_action('distributor_page_pull')
wp-includes/plugin.php:517 
Component: Plugin: distributor-stable

Besides Distributor everything works fine and fast. Hosting has enough resources.
I tried to deactivate other plugins and change theme but it gave no result.
Also i switched between various PHP versions (7.4 -> 8.1) and also no luck.

On both sites Rest Api is available :

Steps to Reproduce

1. Establish connection between sites
2. Go to Pull Content screen
3. Use Query Monitor to catch errors

@vikrampm1 Although I didn't have access to shared hosting, but I tried to replicate the issue in my local with shown configuration and I wasn't able to reproduce it.

@ankitguptaindia @qasumitbagthariya can you double check to see if you are able to reproduce this issue? If not, then we can go ahead and close the issue.
