@JeromeSi interesting error, at least you give me the golang error it's fine

[nerzhul]

It seems it can be due to your local certificate. Seems java client accept it but not the golang http client which is stricter. I'm looking for a workaround to permit it in insecure configurations

Your certificate doesn't have any IP:192.168.1.253 field

[JeromeSi]

In this log, you find the golang error... I'm learning about it.
The certificate are self signed (it's my own little server)

[nerzhul]

@JeromeSi i'm trying to reproduce the problem

[nerzhul]

can you give me the public certificate of your server by mail (contact at unix-experience.fr) i will analyse the SSL issue on it

[JeromeSi]

wait a minute

[nerzhul]

For your usecase with SSL, regenerate a proper certificate with proper SANs (IP/DNS names)

First generate the following openssl.cnf file

[req]
distinguished_name = req_distinguished_name
req_extensions = v3_req

[req_distinguished_name]
countryName = Country Name (2 letter code)
countryName_default = US
stateOrProvinceName = State or Province Name (full name)
stateOrProvinceName_default = MN
localityName = Locality Name (eg, city)
localityName_default = Minneapolis
organizationalUnitName  = Organizational Unit Name (eg, section)
organizationalUnitName_default  = Domain Control Validated
commonName = Internet Widgits Ltd
commonName_max  = 64

[ v3_req ]
# Extensions to add to a certificate request
basicConstraints = CA:FALSE
keyUsage = nonRepudiation, digitalSignature, keyEncipherment
subjectAltName = @alt_names

[alt_names]
DNS.1 = kb.example.com
DNS.2 = helpdesk.example.org
DNS.3 = systems.example.net
IP.1 = 192.168.1.1
IP.2 = 192.168.69.14

Replace DNS entries with yours if you have it, and IP with yours. (if you have 3 IPs, add IP.3 = A.B.C.D)

Next regenerate a private key

openssl genrsa -out nextcloud.key 2048

And generate a signing request

openssl req -new -out nextcloud.csr -key nextcloud.key -config openssl.cnf

Last generate the certificate

openssl x509 -req -days 3650 -in nextcloud.csr -signkey nextcloud.key -out nextcloud.crt -extfile openssl.cnf -extensions v3_req

If all succeed, verify the certificate with the following command

openssl x509 -in nextcloud.crt -text

You must have the following entry: X509v3 Subject Alternative Name:, containing your IPs or DNS names

If it's good, replace certificates of your nextcloud/owncloud instance

[JeromeSi]

I've got new certificate...
a space missing in
"openssl req -new -out nextcloud.csr -key nextcloud.key -config openssl.cnf"

[nerzhul]

i also just released 2.0.2 to show the SSL issue properly in android

[JeromeSi]

mmh. I replace my old certificate by new in my configuration, I reboot my server and no access to my owncloud...

[nerzhul]

Just check your apache/nginx logs it should show you a SSL issue on the startup i think, maybe you inverted key and cert

[JeromeSi]

ok. You're right.
I've got the same error...but I've got the 2.0.1 version

[JeromeSi]

I don't know the line command to update my git repository on my hard disk...I'm searching

[JeromeSi]

Different issue but error

I'm going to sleep

[nerzhul]

at least 2.0.2 really permits to show the certificate error, i should look at this issue asap but i'm tired :)

[JeromeSi]

With app 2.02 on emulated device android 6.0
When I select add an account, I have got this error in logcat :
02-13 19:20:11.396 2875-2911/fr.unix_experience.owncloud_sms E/Surface: getSlotFromBufferLocked: unknown buffer: 0x9f2c3f20
After write server address, login and password, the app crash

[JeromeSi]

But "work" (don't crash when click o Sign in) on other emulated device
Classical error : 02-13 19:32:33.119 3428-4638/fr.unix_experience.owncloud_sms I/GoLog: Get https://192.168.1.253:4433/index.php/apps/ocsms/get/apiversion?format=json: x509: certificate signed by unknown authority

[livingsacrifice]

I'm getting same error as JeromeSi for unknown authority. Is it possible to add option to ignore this issue. Other apps (eg, Davdroid, Nextcloud) don't complaining about the certificate.

[hackitz]

Can you not add the option to allow less secure certs? Like foldersync
