Hello @digitalcreed,
Yes, for a few member states, this issue is occurring.
The cause of the issue is not mentioned on the VIES official website.
We are trying to bypass the issue through development since we can’t validate without VIES working.
We are looking for an option to “turn off” the plugin validation if VIES isn’t working properly.
We will have an option to turn off validation (at the top of the validation tab).
In short, once enabled, it will work smoothly and send every call to VIES. If we get a response with any of the following:
MS_UNAVAILABLE
GLOBAL_MAX_CONCURRENT_REQ
MS_MAX_CONCURRENT_REQ
Then the VAT amount will be removed, and a customizable message will appear, such as “VIES is currently unavailable. You are allowed to place an order, and this order confirmation is subject to VAT validation by the admin.”
Soon we will release a new version with fix and will be informed.
Regards
