Title: Unexpected Network Error Last modified: August 12, 2025 --- # Unexpected Network Error * [sjaelv](https://wordpress.org/support/users/sjaelv/) * (@sjaelv) * [10 months, 4 weeks ago](https://wordpress.org/support/topic/unexpected-network-error-4/) * We use Events Manager Pro with Paypal, when trying to book tickets users can mostly not pay “Unexpected Network Error”, sometimes it does work but not often. Problem is across all browsers and devices, mobile seems to be working slightly less. [https://www.werkbox3.de/vollstaendiger-kalender/](https://www.werkbox3.de/vollstaendiger-kalender/) * (Seems to be the same? issue like [https://wordpress.org/support/topic/unexpected-network-error-3/](https://wordpress.org/support/topic/unexpected-network-error-3/)) * Any hint of what could be causing this / how to resolve? So far we can’t say for sure what causes the rare success. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Funexpected-network-error-4%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 2 replies - 1 through 2 (of 2 total) * Thread Starter [sjaelv](https://wordpress.org/support/users/sjaelv/) * (@sjaelv) * [10 months, 3 weeks ago](https://wordpress.org/support/topic/unexpected-network-error-4/#post-18602852) * [@msykes](https://profiles.wordpress.org/msykes/) : * PayPal payments sometimes work on desktop browsers but consistently fail on mobile devices with a “401: rest_not_logged_in” error in the REST API. * The endpoint affected is `/wp-json/events-manager/v1/gateways/paypal_checkout/ capture`.Bookings seem to work more often when users are logged in. * I have already taken the following steps: * I switched my theme (Enfold by Kriesi) to a standard WordPress theme. The error persisted. * I modified my Apache server’s .htaccess file to ensure the Authorization header is passed. The error persists. * I cleared all caches (plugin and server). * The analysis of network requests on mobile devices shows that the API request is answered with a 401 error, indicating that the authentication for the capture endpoint is not being transmitted correctly. Could you please check if this is a known issue related to mobile usage or specific themes? It seems that the Authorization header or the Nonce token is not being passed to the API correctly on mobile devices. Below you will find the complete curl request data that triggers the error. I hope this information helps you find the problem.
