500 error at display IDP/SP info page

[zsimaiof]

Hello,
i recently am receiving a 500 error (see screenshot here : https://ibb.co/TwQHdjM ) when trying to access various IDP/SP metadata pages . Like for example this one :
https://met.refeds.org/met/entity/https%253A%252F%252Faai.heal-link.gr%252Fproxy%252Fsaml2%252Fidp%252Fmetadata.php/
Is there something wrong in general? Cause it seems like an extended problem.
Thank you in advance.

We are also receiving a 500 error for this link: https://met.refeds.org/met/search_service/?entityid=bibliotech and need this remedied.
