Hi,
As you are now with Wampserver
3.1.6, a solution is to stay temporarily with Apache 2.4.34 and then remove Apache 2.4.37 :
Right-click -> Tools -> Delete unused version -> Apache 2.4.37
then quit Wampserver and reinstall the Apache 2.4.37 addon.
Another solution is to Restore the original libcrypto and libssl files of the apache version used:
In the folder wamp(64)/bin/apache/original_libcrypto_libssl/ choose and open the folder that corresponds to the Apache version used, for example apache2.4.37_x32 for Apache 2.4.37 32bit then copy the two dll files found there into the folder wamp/bin/apache/apache2.4.37/bin/ by overwriting the files or symbolic links found there.
Be careful with 32 or 64 bit versions.
