cURL error28

Hi there, I receive the following error when testing the communication:
Exception: cURL error 28: Connection timed out after 10000 milliseconds#0 /home/www/web286/html/transferaustria.org/wp-content/plugins/mycryptocheckout/vendor/mycryptocheckout/api/src/v2/wordpress/API.php(121): mycryptocheckout\api\v2\API->parse_response() #1 /home/www/web286/html/transferaustria.org/wp-content/plugins/mycryptocheckout/vendor/mycryptocheckout/api/src/v2/API.php(312): mycryptocheckout\api\v2\wordpress\API->send_post() #2 /home/www/web286/html/transferaustria.org/wp-content/plugins/mycryptocheckout/vendor/mycryptocheckout/api/src/v2/API.php(321): mycryptocheckout\api\v2\API->send_post_with_account() #3 /home/www/web286/html/transferaustria.org/wp-content/plugins/mycryptocheckout/src/admin_trait.php(977): mycryptocheckout\api\v2\API->test_communication() #4 [internal function]: mycryptocheckout\MyCryptoCheckout->admin_tools() #5 /home/www/web286/html/transferaustria.org/wp-content/plugins/mycryptocheckout/vendor/plainview/sdk/wordpress/tabs/tabs.php(328): call_user_func_array() #6 /home/www/web286/html/transferaustria.org/wp-content/plugins/mycryptocheckout/src/menu_trait.php(136): plainview\sdk_mcc\wordpress\tabs\tabs->render() #7 /home/www/web286/html/transferaustria.org/wp-includes/class-wp-hook.php(308): mycryptocheckout\MyCryptoCheckout->admin_menu_tabs() #8 /home/www/web286/html/transferaustria.org/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters() #9 /home/www/web286/html/transferaustria.org/wp-includes/plugin.php(517): WP_Hook->do_action() #10 /home/www/web286/html/transferaustria.org/wp-admin/admin.php(259): do_action() #11 /home/www/web286/html/transferaustria.org/wp-admin/options-general.php(10): require_once(‘/home/www/web28…’) #12 {main}

I checked all options that you listed, but I didn’t change anything except from adding an additional wallet. Since then (about 5min ago) everything worked fine.

Can you please help?

Thanks and best regards
