[BUG]: Cant Auth, seems like it's trying to make a IPv6 connection on IPv4 network/internet.

[MarjovanLier]

Using https://github.com/xelaj/mtproto/blob/main/examples/auth/main.go to try auth with my app ID and hash returns the floowing error.

@MarjovanLier Thanks for creating this issue!

Noted your problem, i'll try to find fix as fast as i can (sorry, don't have enough time to maintain this project, still trying to find additional maintainer)

I am suffering a similar problem, in my case the error is the following:

panic: sending AuthSendCode: recreating connection: can't connect: setup connection: dialing tcp: dial tcp [2001:67c:4e8:f004::b]:443: connect: network is unreachable

This address comes from here

mtproto/mtproto.go

Line 417 in 5eb6237

newIP, found := m.dclist[e.AdditionalInfo.(int)]

[igolaizola]

I've just discovered that wsl2 hasn't support for IPv6, that's why I am getting a network error: microsoft/WSL#4518

I'll try directly from windows host.

[Kliton]

Same:

panic: sending AuthSendCode: recreating connection: can't connect: setup connection: dialing tcp: dial tcp [2001:67c:4e8:f004::b]:443: connect: no route to host

Any update?

[waybackarchiver]

Try the latest commit d0990b5

[Kliton]

@waybackarchiver Already tried, but nothing changes.
panic: sending AuthSendCode: recreating connection: can't connect: setup connection: dialing tcp: dial tcp [2001:67c:4e8:f004::b]:443: connect: no route to host

What i have noticed is that also if i use "ping6 2001:67c:4e8:f004::b" on my macbook i can't reach the data center.
So the problem is not in the ip format but maybe i just can't ping it with my macbook ( and is really strange ).
When i ping it with a online ping service i can ping the ip.

Any suggestion?

[waybackarchiver]

It looks like can not connect the Telegram server over IPv6.

I guess should add an option to skipping IPv6 address at

mtproto/telegram/common.go

Lines 119 to 125 in d0990b5

	for _, dc := range config.DcOptions {
	if dc.Cdn {
	continue
	}
	dcList[int(dc.ID)] = net.JoinHostPort(dc.IpAddress, strconv.Itoa(int(dc.Port)))
	}

[Kliton]

I've filtered all ipv6 addressess:
if dc.Cdn || dc.Ipv6 {continue}

Now is connecting to this ip:
PHONE_MIGRATE_X: need to go to DC with ip:port -> 149.154.166.120:443

And now i have this error:
panic: (code 4294966892)

Any suggestion?

[waybackarchiver]

It is a known issue same as #65

[Kliton]

So actually the lib isn't working at all for auth, right?

[waybackarchiver]

I only got a successfully auth at the example code (examples/auth/main.go), maybe I missing something.

[Kliton]

Solved.
The problem was that i was getting PHONE_MIGRATE_4, so i had to switch to Dc[4] but dc[4] has two different addresses and the code is using the last ip ( because is replacing the ip in the dc list with key 4 ).

Change the code in "NewClient", telegram.Common.go

for _, dc := range config.DcOptions {
		if dc.Cdn {
			continue
		}
		if strings.Con; tains(dc.IpAddress, ":") {
			// ipv6
			continue
		}

		// Prevent replacing ip if one DC has more ips ( in this way i'm preserving the first ip that i have)
		_, ok := dcList[int(dc.ID)]
		if ok {
			continue
		}

		dcList[int(dc.ID)] = dc.IpAddress + ":" + strconv.Itoa(int(dc.Port))
	}

[Kliton]

And for the error: panic: (code 4294966892)

I solved as yabibi suggested in issue #65
After PHONE_MIGRATE_X you have restart connection with the dc address pointed out by message PHONE_MIGRATE_X

[waybackarchiver]

ref: #22 (comment)

[libai0610]

And for the error: panic: (code 4294966892)

I solved as yabibi suggested in issue #65 After PHONE_MIGRATE_X you have restart connection with the dc address pointed out by message PHONE_MIGRATE_X

I have do the change :

for _, dc := range config.DcOptions {
if dc.Cdn {
continue
}
if strings.Con; tains(dc.IpAddress, ":") {
// ipv6
continue
}

	// Prevent replacing ip if one DC has more ips ( in this way i'm preserving the first ip that i have)
	_, ok := dcList[int(dc.ID)]
	if ok {
		continue
	}

	dcList[int(dc.ID)] = dc.IpAddress + ":" + strconv.Itoa(int(dc.Port))
}

Then I got panic: (code 4294966892)

How to resove it ? Could you help me, and show the detail? @Kliton

[quenbyako]

This is soooooo sucks that i developed this project and i completely lost a context about all issues....

Fuck, i need to make pipelines for problem solving...

@libai0610 sorry that current community can't help you on right level, i'll try to look what's the problem and maybe come back to you, sorry for super low support level.

[libai0610]

Thank you very much. I believe it will be better and better with everyone's efforts. @quenbyako

[Robtzz]

I only got a successfully auth at the example code (examples/auth/main.go), maybe I missing something. main.go), maybe I'm missing something.

I can't even succeed with an example

[Robtzz]

And for the error: panic: (code 4294966892)对于错误：panic：（代码4294966892）

I solved as yabibi suggested in issue #65 I solved it as yabibi suggested in issue #65 After you have restart connection with the dc address pointed out by message 'PHONE_MIGRATE_X' 'PHONE_MIGRATE_X' restart with message ' PHONE_MIGRATE_X PHONE_MIGRATE_X indicates the DC address after the connection

Brother, I need your help too

And for the error: panic: (code 4294966892)对于错误：panic：（代码4294966892）
I solved as yabibi suggested in issue #65 After you have restart connection with the dc address pointed out by message PHONE_MIGRATE_X``PHONE_MIGRATE_X我按照 yabibi 在问题 #65 中的建议解决了，在您重新启动与消息 PHONE_MIGRATE_X PHONE_MIGRATE_X 指出的 dc 地址的连接后

I have do the change :我已经做了改变：

for _, dc := range config.DcOptions {对于 _，DC ：= 范围配置。DcOptions { if dc.Cdn { 如果 dc.Cdn { continue 继续 } if strings.Con; tains(dc.IpAddress, ":") {if 字符串。缺点;tains（dc.IpAddress， “：”） { // ipv6 IPv6协议 continue 继续 }

	 Prevent replacing ip if one DC has more ips ( in this way i'm preserving the first ip that i have)
	_, ok := dcList[int(dc.ID)]
	if ok {
		continue
	}

	dcList[int(dc.ID)] = dc.IpAddress + ":" + strconv. Itoa(int(dc.Port))
}

Then I got panic: (code 4294966892) github.com/xelaj/mtproto.check (...4294966892) github.com/xelaj/mtproto.check（... ）

How to resove it ? Could you help me, and show the detail? How to recover it? Can you help me and show the details? @Kliton

Did you finally deal with him?
