Hi,

I have a problem. After migration to new data center in ERP system I see an warning "Communication error, CPIC return code 020, SAP return code 456".
dev_w1 show:
LOG R49=> ThReceive, CPIC-Error (020456) [thxxhead.c 8145]
LOG R5A=> ThReceive, CPIC-Error (58806080) [thxxhead.c 8150]
LOG R64=> ThReceive, CPIC-Error ( CMSEND(SAP)) [thxxhead.c 8155]
RFC 3823 CONVID 58806080
CMRC=20 DATA=1 STATUS=1 SAPRC=456 ThSAPCMRCV
RFC> ABAP Programm: SAPLSCMS_FE_RFC (Transaction: CV03N)
RFC> User: USER(Client: 100)
RFC> Destination: SAPHTTP (handle: 4, DtConId: 594A6CE7D730F1A7911400
RFC> Called function module: RFC_PING

I know that the program SAPLSCMS_FE_RFC is related to Content Server.
How to resolve this problem?
