Hello, I am using libcsoap in C language to make web service call to HTTPS url. libcsoap uses nanohttp to connect to openssl. All above was working well in CentOS version less then 7. In CentOS 7, it is not working and behaving as below: In the first try of connection it is working well and gets response from web service. In the second try onwards it gives error - SSL_R_UNABLE_TO_LOAD_SSL2_MD5_ROUTINES all the time. If I restart whole my application then again it works once and then again second time onward above error. Here is the version information: #rpm -qa|grep openssl openssl-libs-1.0.1e-42.el7.9.x86_64 openssl-debuginfo-1.0.1e-42.el7.9.x86_64 openssl-1.0.1e-42.el7.9.x86_64 openssl-devel-1.0.1e-42.el7.9.x86_64 Please Advise. - Mitesh -------------- next part -------------- An HTML attachment was scrubbed...
