ssl.https TLS 1.3

[Thomas]

Hi
Is there available ssl.https with TLS 1.3 support?

I'm getting
error:1409442E:lib(20):func(148):reason(1070)


when I try:

Code:

url=https://weatherstation.wunderground.com/weatherstation/updateweatherstation.php?softwaretype=PWS+Jung+2225WSU&solarradiation=154.96&humidity=78.08&dewptf=57.54&baromin=29.9834279983681&tempf=64.58&winddir=200&ID=MYID&windspeedmph=4.94377&action=updateraw&dateutc=2020-11-02+11%3A55%3A11&PASSWORD=XXXX

https = require("ssl.https")

res, code, hdrs, stat = https.request(url)
log(res, code, hdrs, stat)

and I think it's TLS related issue.
I tried

Code:

local r, c, h, s = https.request{
    url = url,
    protocol = "tlsv1.3"
}

but it says 1.3 is not supported.

TLS 1.3 works in 2020 RC firmware. You don't have to specify TLS version there as the SSL library will automatically negotiate the highest supported version by both client and server.
You can request https://check-tls.akamai.io/v1/tlsinfo.json to quickly check TLS 1.3 support.
