Hi. I'm using 0.2.6.

I am running the HTTP example and when I execute the following call in the loop function:

bool updatedNeeded = esp32FOTA.execHTTPcheck();

...I receive the message error in the issue title.

There is well a manifest_url variable:

const char *manifest_url = "http://192.168.1.100/ota/fota.json";

...and this variable is the one referenced by the following call in the setup() function:

esp32FOTA.setManifestURL( manifest_url );

Any ideas ?

Thanks !
