[Koha] Connection timed out whenever I try a Z39.50 search

[Δημήτρης Δαλαγιώργος]

Dear all,

I have added several Z39.50 interfaces to my library but for some reason
searching through Z39.50 no longer works; I get a connection timeout error
message.

Where should I start looking to remedy this?

Kind regards,
