It is all going to depend on the log entries, I can not give a blanket statement, nor list every single possibility. :)

I've pmed you the Last 70 lines of a2s.in.access.log a2s.in.error.log

have you got my pms , because I've been waiting for you reply the whole day :(

@ozzy47 seems to be busy , anyone else can help me here ? I can pm you my server logs if that will help

Umm,
First off, it has not been the whole day. It has been 6 hours since you PM'd me.

Secondly, I did not ask you to send me a PM, you should post the logs in the thread so all users can help.

Third, I have a full time job and help people out here in my spare time, I do not get paid to provide support, nor did you pay for support.

Fourth, when you are asking for free help, a little patience is needed, as this site is ran by volunteers, that do this in their spare time.

Now with that out of the way, I am going out for a bit, and I can take a look at the logs when I get a chance. :)

You can PM me the logs if you want, I'd be interested in looking at them.

Looking over what you PM'd me, I see no attempts of PayPay in the access logs, or error logs.

I would ask your host what the issue is, as PayPal can find your site under HTTP, but not HTTPS

sorry for bothering you , I've just seen that you're online at the time that I was waiting for you , you could simply tell me that you're busy and I can pm the logs for someone else , since I can't post the logs publicly due to security , I may get DDoss attacks easily since the website IP is shown in the logs

Not a problem. I looked them over and said this in another post.

if that's the case , why members can buy points using paypal and get the points !?

Yeah I forgot about that. Perhaps ask PayPal,tell them when your site is under HTTP, it connects to the script, payment_gateway.php with no problems, but when you use HTTPS, it does not. As I see nothing in the logs that PayPal reached the server.

Keep in mind that if you see a member online they actually might NOT be online. vBulletin has a built in time delay for showing the users in the WGO area. The delay is 15 minutes so just because you see someone online they may not actually be there they might have been there 10 minutes ago.

Actually, the only time I am not showing as online is when I loose power. My pc is on 24/7 and I always have a vB.org tab open.

LOL mine is on 24/7 too but I do not stay on vb.org. :)

Which would not prevent your session to time out, would it? As long as you don't do anything, just having the tab open won't keep you "alive", I think.

Yeah in that case I would think it would although I've come on here and he was not on. But that may have been because he lost power as he said. I was simply stating that about the 15 minutes to the OP since he was waiting on pins and needles lol. Sometimes people do not realize that there is a 15 minute lag if they are new to vB or they are just not aware of it.

Nah, I totally agree with that. People really need to have some patience. Even if Ozz was around, he's fully in his rights to do other things first as he sees fit - after all, there's no priority support around here. And expecting him to sort of check out first after a unasked for pm really stresses it somewhat...

Agreed. :)

I looked at the logs and didn't see any paypal activity, but I also noticed that the 70 lines of access log covered less than 1 minute, so I don't think any conclusions can be drawn from that.

I looked at the code for the points mod that does work with paypal, but it doesn't look llike it uses the IPN message. I don't know how it works without it.

I tried to go to https://removed.com using chrome this morning and got this message:
which is kind of what I was originally thinking, that there may be an SSL handshake issue between paypal and your server. I don't know how you'd go about debugging that. I think apache has an ssl error log, (if that's what you're using). ETA: or, as I think I mentioned earlier, maybe you can run an http server that allows access only to payment_gateway.php.

I pmed him at that time because I went to his profile and saw that his is replying in other threads , so I pmed him .

I agree too , sorry I didn't want to be a bother , I've just pmed ozzy because he was interested in the server logs.

Understood. Although, as a general rule, do not PM members here for private assistance unless asked to. And if you want help fast, make sure as many members as possible have access to all relevant information. For example, you surely realize that it does not take more than a simple find/replace all in your favourite editor to anonymize your IP address in your log.

New update guys : we have disabled SSL in our forum ,and we've gone back to HTTP , but still the same issue , I don't know what the problem now , I have been thinking the whole time that it's SSL issue but now I found that's not , so what is the problem , I think something in my server , like a firewall or something.

Like I said, I did not see any attempts from PayPal in the logs you sent me. So one of three things.

1) They did not show cause there was no action from PayPal at the time.
2) A issue with PayPal.
3) A issue with your server.

IMO it is number 3, so you would need to contact your host to have then figure out what the issue is. Or perhaps #2, then you would need to contact PayPal. :)

Final update : I've fixed everything , the suscription system is working now , it was an issue with my server , I've disabled the firewall in my server and everything works fine, thanks everyone for all your efforts.

Glad to hear it's finally sorted. :)

thanks for everything , one last thing , my hosting told me that I can't keep my firewall disabled , so I have to whitelist paypal , do you know their IP , I hear they change it everytime ?

Do they HAVE to have the IP address? Couldn't they allow with just the domain instead?

You can find the IP's and domain names of PayPal here: https://ppmts.custhelp.com/app/answers/detail/a_id/92
If possible with your firewall, whitelist *.paypal.com.

Yeah that is what I was thinking whitelist paypal.com since if they keep on changing the IP address. It would be a nightmare to try and keep up with the IP address changes in that case, so there must be some way to just add the domain instead. You may want to ask your host if its possible and tell them that paypal changes its IP address regularly.

Er ok, wow. Well whenever Paypal changes their IP address you will continue to have this problem. Perhaps the host can implement some sort of fix?

Yeah it's called get a better firewall. :)

Just out of curiosity, are we talking about incoming or outgoing connections? If it's incoming, then I can see why white listing by domain name is a problem. Do any firewalls actually work that way?
