Here the output of the error: dig 21-Mar-2019 13:42:13.473 ENGINE_by_id failed (crypto failure) 21-Mar-2019 13:42:13.474 error:25066067:DSO support routines:dlfcn_load:could not load the shared library:crypto/dso/dso_dlfcn.c:119:filename(/usr/lib/engines-1.1/gost.dll): No such file or directory 21-Mar-2019 13:42:13.474 error:25070067:DSO support routines:DSO_load:could not load the shared library:crypto/dso/dso_lib.c:162: 21-Mar-2019 13:42:13.474 error:260B6084:engine routines:dynamic_load:dso not found:crypto/engine/eng_dyn.c:414: 21-Mar-2019 13:42:13.474 error:2606A074:engine routines:ENGINE_by_id:no such engine:crypto/engine/eng_list.c:334:id=gost dig: dst_lib_init: crypto failure host 21-Mar-2019 13:42:16.407 ENGINE_by_id failed (crypto failure) 21-Mar-2019 13:42:16.408 error:25066067:DSO support routines:dlfcn_load:could not load the shared library:crypto/dso/dso_dlfcn.c:119:filename(/usr/lib/engines-1.1/gost.dll): No such file or directory 21-Mar-2019 13:42:16.408 error:25070067:DSO support routines:DSO_load:could not load the shared library:crypto/dso/dso_lib.c:162: 21-Mar-2019 13:42:16.408 error:260B6084:engine routines:dynamic_load:dso not found:crypto/engine/eng_dyn.c:414: 21-Mar-2019 13:42:16.408 error:2606A074:engine routines:ENGINE_by_id:no such engine:crypto/engine/eng_list.c:334:id=gost host: dst_lib_init: crypto failure In the attachment you find the cygcheck report.
