The website of this connection is not available

Hello, I have downloaded and activated the ‘ SumUp Payment Gateway For WooCommerce ‘ plugin. When I go to ‘connect account’, I get the error ‘The website of this connection is not available’. How do I fix it? Thanks. I’m also receiving the same message when trying to connect. Plus, this Warning is repeated twice when plugin is activated :- Warning : Trying to access array offset on false in /########/wp-content/plugins/sumup-payment-gateway-for-woocommerce/includes/class-wc-sumup-logger.php on line 25 Have tried disabling all plugins except woocommerce & Sumup. PHP Version 8.4 WordPress Version 6.9.1 Can we have some guidance please. I believe this issue was introduced in the latest release, it seems all wp-json/sumup_connection/v1 endpoints which are used on the connect flow now requires authentication and an user with admin permissions. This are the changesets: https://plugins.trac.wordpress.org/changeset/3454868 The problem is when SumUp need to execute callback for completing the configuration and validation process, these request are unauthenticated: 52.48.211.42 - - [11/Feb/2026:19:04:41 +0100] "GET /wp-json/sumup_connection/v1/validate HTTP/1.1" 401 116 "-" "Resteasy Reactive Client" 52.48.233.7 - - [11/Feb/2026:19:08:44 +0100] "GET /wp-json/sumup_connection/v1/validate HTTP/1.1" 401 116 "-" "Resteasy Reactive Client" 52.48.211.42 - - [11/Feb/2026:19:11:07 +0100] "GET /wp-json/sumup_connection/v1/validate HTTP/1.1" 401 116 "-" "Resteasy Reactive Client" 52.48.211.42 - - [11/Feb/2026:19:11:46 +0100] "GET /wp-json/sumup_connection/v1/validate HTTP/1.1" 401 116 "-" "Resteasy Reactive Client" Obviously, no bearer token or user creds are sent to SumUp servers on this flow and SumUp receives Unathorized Request when executing the callback to our wordpress, also SumUp UI is not so verbose so you cannot figure out what is really happening. I am also having this issue. Really frustrating! I am getting these errors which I think all relate to the same core problem. Hope this gets sorted soon! 2026-02-16T19:54:39+00:00 Debug ==== SumUp Version: 2.7.10 ==== Merchant ID: === Start Log === Error on get access token.
