This answer seems relevant: https://stackoverflow.com/a/39217099/232775 .
The link in the answer is no longer available; the current link is
https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/4906705/ .

The obvious workaround would be to retry the request, because the error
happens randomly depending on the value of a Diffie-Hellman ephemeral
key parameter.
