SSL Wrong Version error

dgiersz_cuyahoga — Mon, 17 May 2021 18:20:00 GMT

We have a proxy for all our web traffic and use the proxy_host/proxy_port parameters when connecting to AGOL from Notebooks in Pro. This worked fine until we upgraded to Pro 2.8 and we now receive SSL errors:

--------------------------------------------------------------------------- SSLError Traceback (most recent call last) In [3]: Line 1: gis = GIS(proxy_host='XXX.XXXXXXXX.XX', proxy_port=XXXX, verify_cert=False) File C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\Lib\site-packages\arcgis\gis\__init__.py, in __init__: Line 359: raise e File C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\Lib\site-packages\arcgis\gis\__init__.py, in __init__: Line 343: trust_env=kwargs.get("trust_env", None)) File C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\Lib\site-packages\arcgis\gis\_impl\_portalpy.py, in __init__: Line 173: self.get_properties(True) File C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\Lib\site-packages\arcgis\gis\_impl\_portalpy.py, in get_properties: Line 1138: raise e File C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\Lib\site-packages\arcgis\gis\_impl\_portalpy.py, in get_properties: Line 1126: resp = self.con.post(path, self._postdata(), ssl=True) File C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\Lib\site-packages\arcgis\gis\_impl\_con\_connection.py, in post: Line 690: "Please set verify_cert=False due to encountered SSL error: %s" % err) SSLError: Please set verify_cert=False due to encountered SSL error: HTTPSConnectionPool(host='www.arcgis.com', port=443): Max retries exceeded with url: /sharing/rest/portals/self (Caused by SSLError(SSLError(1, '[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1091)'))) ---------------------------------------------------------------------------

The URLs for both HTTP and HTTPS traffic are the same for our proxy.

Has anyone else encountered this?

Happened the same to me when upgrading to 2.8, didn't find any solution.

Would it be possible to define something in .condarc file? Downgrading to AGPRO 2.7 might help, until ESRI solves this problem.

I did put our proxy in the .condarc file but it didn't help (other than conda could connect to the online repositories).

I've opened a support case with Esri, hopefully they can help.

Downgrading to 2.7 does work and we're also using AGOL Notebooks in the meantime.

I have encounter the same problem. I don't have any solutions, but I wanted to post here as extra evidence that this needs to be addressed.

I have the same problem on two computers since installing 2.8. A solution other than reinstalling ArcGIS Pro 2.7 would be nice.

Was Esri able to solve the problem?

I was told it was related to #BUG-000140216 and the only workaround is using ArcGIS Pro 2.7 or earlier. We also moved some of our stuff to AGOL Notebooks to get around the issue.

Thank you, that's good to know. Unfortunately we need to be able to connect from a local machine to AGOL (for automated backup tasks) so I guess we'll have to go back to 2.7 for now.

I was just notified this bug has been updated to 'In Product Plan' so here's hoping it doesn't take too long.

Hi,

I found a solution for arcgisPro 2.9.2. In my project we use the arcgis.gis.server.server() to make the new request see https://developers.arcgis.com/python/api-reference/arcgis.gis.server.html. In there there is a parameter that is setting the difference between HTTPS and HTTP. Apperantly the default is True (or it needs to be explicitly mentioned to be false). In my case adding the parameter to false fixed the problem. It would be better of course to use the HTTPS.

The real root cause is the update of the Urllib3 python library. In v1.25.x HTTPS was not supported and every hTTPS call you did was transformed to HTTP. But in v1.26.x is is supported and you should update your calls. I suppose Arcgis Pro 2.7 has the 1.125 version and the 2.8/9 had the 1.26 version but I haven't checket that. https://github.com/urllib3/urllib3/issues/1850.

Thank you for this @BartGis5, helped me to fix a critical script for my org!

Long enough. I've just been told by Esri Canada that the fix will show up in version 2.0.1 sometime in June/July.

Re: SSL Wrong Version error

OrrGvili — Sun, 26 Jun 2022 08:54:27 GMT

with version 2.0.1 of the api
this method of using the proxy is the only one that working

# Usage Exmaple 9: Using a Proxy
proxy = {
'http': 'http://10.10.1.10:3128',
'https': 'http://10.10.1.10:1080',
}
gis = GIS(proxy=proxy)

we can move to arcgis pro 3

AdminWPZ — Wed, 13 Jul 2022 08:43:49 GMT

Did you test it with ArcGIS Pro 3? Anyone?

Re: SSL Wrong Version error

OrrGvili — Thu, 14 Jul 2022 05:57:09 GMT

yes the problem solved with api 2.0.1 that came with ArcGIS Pro 3
we updated to pro and problem solved

Ah, thanks for clarifying, I misunderstood. And thanks for posting the solution!
