@Sil-B @fazed We are currently unable to reproduce this issue on our own testing environment. Could you please give us some additional information? What checkout extension are you using etc. Thank you in advance.

[Sil-B]

@Buckaroo-Rens Thanks for the quick reply. For this project we are using the Amasty One Step Checkout :(. I did not try it with the native checkout.

[Buckaroo-Rens]

@Sil-B Could you please test with native checkout? We do not support the Amasty One Step Checkout currently.

@Buckaroo-Rens I've tested it with native checkout and default lume theme. Same issue:

[2020-02-11 13:21:13] main.CRITICAL: SOAP-ERROR: Encoding: string '6\xe9...' is not a valid utf-8 string {"exception":"[object] (SoapFault(code: 0): SOAP-ERROR: Encoding: string '6\\xe9...' is not a valid utf-8 string at /home/xxx/magento2/vendor/buckaroo/magento2/Soap/Client/SoapClientWSSEC.php:33)"} []

@Sil-B, we've managed to fix our issue by flushing the WSDL cache. Apparently when upgrading PHP from < 7.3 to >= 7.3, the cached WSDL files are borked.
