[dudzikmichal@wp.pl]

Hi, I am writing with a request for help. It is about a causing a problem when searching for records by z39.50. (Koha version: 20.05.05.000). On the printscreen ( ibb.co ibb.co ) you will see responses for the following messages and one or two search results.    It looks like it cannot retrieve some records. There are no errors in the intranet-error.log. The address of the server z39.50 from which I am searching for records is: hostname: eu.alma.exlibrisgroup.com:1921 database: 48OMNIS_NLOP   I testing in yaz-client but when I show all records then yaz is stopped in Sent presentRequest.   yaz-client -f conf_bn  Connecting...OK.  Sent initrequest.  Connection accepted by v3 target.  ID     : 81  Name   : Aleph Server/GFS/YAZ  Version: ALEPH 20/1.1.1.1/2.1.32  Options: search present delSet triggerResourceCtrl scan sort extendedServices namedResultSets  Elapsed: 0.110043  Sent searchRequest.  Received SearchResponse.  Search was a success.  Number of hits: 4, setno 1  records returned: 0  Elapsed: 0.169132  Sent presentRequest (1+4).    Koha is visible in the local network. The server is on 192.xx.xx.xx and I am connecting via VPN and it gets IP 10.xx.xx.xx. Is this a problem with network??   Let me know, thank you in advance.   Regards  Michal
