I'm getting this error every time I try to use VSTAR over the last few days. There's no problem with the internet connection, and I have the latest Java installed. Any suggestions as to what's happening?

I have occasionally seen this

I have occasionally seen this intermittent problem and saw it again for about an hour or two last Thursday. At the same time I was able to use LCG etc on the AAVSO web just fine. That leads me to conclude that it was a problem with access to the database host from outside (as opposed to from server side which is how LCG and other web apps would make use of it).

I can access it just fine now and VStar CHOICE course participants seem to be making use of it.

It's annoying when problems are intermittent, I understand.

How is it at the moment for you?

There will in future, I hope, be a web service based approach to accessing AID that I want to use instead of the current approach. But that's currently vapourware. When it becomes something more than that, I'll be making noise about it. :P

When I am trying to use “File / New star from APASS …” or “Tool / Plug-in Manager” the VStar ask me for the AAVSO user name and password but does not recognize them and return me the message for incorrect data. (see the attached images)

Probably I am missing something or I am not authorized to use this functions.

Hi Velimir

I don't see any images attached to your post.

A couple of questions:

  1. What version of VStar are you using? Does the title bar say 2.16.2?
  2. Does the same username and password authenticate correctly when logging into the AAVSO web page?

Note that you need to be an AAVSO member to use BSM and APASS plug-ins but not to use the plug-in manager.

Hello Velimir

About June 10th, all the passwords had to be reset (Changed) as a result of the security breach.  Have you changed your password since then?

Hi David and Gary,

Sorry but I have forgotten to attach the images. Now it is done.

I have reset and change my password after the security breach.

  1. I am using VStar 2.16.2.
  2. I am a member of AAVSO and I am logging without any troubles to AAVSO web page.

Hi Velimir Thanks for that

Hi Velimir

Thanks for that suggestion Gary. It crossed my mind then I forgot to mention it.

I wonder whether this is related to VStar's use of the new authentication implementation. Have you tried logging into Zapper, SeqPlot, or SunEntry? That may help to narrow things down further since these tools and VStar talk to the same authentication interface now.

David

Hi David,

Not any problem to log-in to Zapper, SeqPlot, or SunEntry, everything works.

The situation with VStar remains the same. I cannot log-in to "File / New star from APASS …”

Hi David,

The other thing that I notice is the use of a comma by default while in my system is necessary to use a point. I mean the function “Analysis / Phase Plot”. I have to change the comma with a point manually each time otherwise it returns wrong Period and Epoch in the graph. When I manually change them everything is going well. It is not a problem and I can to do this but I decide just to mention it.

Please compare the numbers in Phase Plot window and these below star title in the attached images. I hope do not forget to attach them again.

Hi Velimir

Given the nature of the phase plot problem, I've started a separate forum topic for this:

  http://www.aavso.org/numbers-and-locales-eg-05-vs-05-vstar

Could you reply there re: that issue?

Thanks.

David

Hi Velimir Okay, I'll have to

Hi Velimir

Okay, I'll have to talk with Sara and Will about this tonight (it's Monday morning in Australia). It may be related to how VStar is talking to the new authentication API.

Are others seeing this problem?

Hi Velimir,

I just did a quick check of our records of your account information (membership status, the fact that you have changed your password since the big reset, etc.) and everything seems to be in order from that point of view. David and I will talk about the authentication procedure to try to solve this mystery.

In the meantime, would you please check to see that you don't have two copies of the APASS plugin installed in your computer - the old one as well as the new one? If there is only one copy, it might be a good idea to delete it and re-install it again to be sure you have the latest. I know for certain that the old version will no longer work. Also please remember that after you install the new version, you must close VStar then open it again for it to take effect.

Please let us know if that helps. If not, we will continue to pursue other possibilities.

Best regards, Sara

Thanks Sara.

Velimir, can you also tell us whether the time taken for you to see the "Invalid username or password" message is small? Does it seem to be going off to check against a server (a couple of seconds) or returning with the message immediately?

David

First time use of VStar?

Also, can you tell us whether or not you ever used your username and password with VStar before 2.16.2 (this release).

Hi Sara, hi David,

I highly appreciate your efforts.

Firstly for Sara questions:

I have not two copies of APASS plugin in the plugin folder. I have attached two screenshots for you.

I always have used the web based VStar, not installed locally in my computer. Now I have got the latest plugins from the AAVSO web site: vstar-plugins-2.16.1 and replaced the old ones. The situation is the same, everything works well but only “File / New star from APASS …” does not accept my user name and password.

Secondly for David questions:

  • The message “Invalid user name and password” appears  with the speed of lightning smiley
  • I cannot remember exactly but probably I must have used my user name and password before 2.16.2 release

Best regards,

Velimir
