Alteryx Connect - SMTP issue

Hi All,

Receiving the below error when attempting to reset passwords, this works for our Alteryx Gallery though. I've had a look in connect and on our connect server and I'm not sure where to configure the SMTP settings for this. I can't see a config app similar to the one for Gallery where settings can be changed and if I select 'change' in apps/programs it mentions an uninstall module which I'm not confident to proceed with pressing next.

is there a config in program files somewhere I can amend this?

SEVERE: Servlet.service() for servlet [xf3-standalone] in context with path [] threw exception [Request processing failed; nested exception is cz.semanta.xf3.XformsException: Could not send e-mail to UserEmailladress] with root cause

javax.mail.AuthenticationFailedException: 535 5.7.3 Authentication unsuccessful

thanks

Dear RhysPickett,

My name is Petr and I am from Alteryx Connect team. I will try to help you with mail server settings.

According to error message it looks like that your mail server is configured the way, that allows you to send message without authentication.

(There can be some list of trusted hosts where he just takes message and send it.)

Please could you confirm that?

Unfortunately in curent version of installer there is no checkbox for that setting.

However we still are able to manage this setting in configuration.

If this is the case, I suggest that we schedule quick debug session I will try to guide you throw the process.

If not lets plan session too and I will have a look for settings and values throw installation.

I can promise that new installer, who will be released very soon will have this part completely changed and new interface will allow you to setup and TEST your mailserver without leaving the installer. Also the mail server settings can be modified without need of deinstalling.

Hi all,

I will mark this as resolved. I managed to correct the issue in Connect version 2.0, now when logging into connect I get the options to configure SMTP settings in 'Administration' as opposed to the ac_config file in the connect directory (which doesn't exist in v 2.0).

What corrected the issue was that I was passing domain\username and password fields, when I left these blank, the e-mails started working. I believe because I was passing credentials the request was attempting to authenticate and hence 'no authentication mechanisms supported on both the client and server'.

Hope this helps any other users experiencing the same issues,

thanks.

@RhysPickett - the SMTP settings are set during install, but the config file can be found at %ProgramFiles%\AlteryxConnect\ac_work under the file ac_config.xml.

As with all edits to config files, please make a backup prior to making any changes. More info on setting the SMTP settings can be found in the Help.

Thanks for you reply Sophia,

I have checked the XML and can confirm everything is set to the same settings as our Alteryx Gallery server. The issue must lie within the <SMTPPasswordEncrypted> field. Are you aware of any way I can get this changed without the reinstallation? as previously discussed the emails work in gallery but not for connect, and the 'from' email, host, username, port and SSL options are set to the same.

I had similar issues. After many uninstalls and reinstalls and working with support, I learned a few things that may (or may not) apply:

For the SMTP user name, I had entered it as "domain\username." Connect will throw out the backslash, making it an invalid user name. Support recommended using "username@domain." In my case, it turned out that I didn't need the domain at all.
It appears that Connect does not allow some characters in the SMTP user password. I proved this by changing from the account we use for Alteryx Server (which includes an "@" in the password) which didn't work, to my own personal account (I am an admin), which only uses letters and numbers in the password, and that worked. I asked for documentation of what letters were disallowed, and they claimed that only $ and \ were disallowed. I had already proven that to not be true. So at this time I don't know what letters work and what don't, other than to say letters and numbers work, and @, $ and \ do not.

I hope that helps. Try experimenting and let us know what you learn.

Ah that's great, the password does contain invalid characters as you mentioned below so looks like this will need to update! I will experiment with taking the domain out and changing to the SMTP address for username providing this does not resolve the issue,

Many thanks for this!

I will be back to confirm if this has worked and close as resolution

kind regards

Unfortunately still having issues, I think the password field must have been configured incorrectly when the person had set this up. If I go ahead to reinstall through control panel, will this keep a backup of the activity that's already undergone (user account creations, data sources etc)? Or would I need a copy of some directories to reimport once I've reinstalled?

Also, just wanted to enquire with this message; No authentication mechanisms supported by both server and client. With us allowing the servers IP to the relay connectors in exchange (allowing it to send mail) I notice that only TLS is selected for authentication and not basic authentication - do you think this is required in order for connect to speak to our exchange server? Only because the only thing I could whittle it down to was password if not this, as I would imagine it would have returned a authentication unsuccessful or similar message instead. failing this I will try contact support to see If I can get any movement on this,

many thanks

Rhys
