Tracker *Bug Feature Task

Subject *

Description (sorry if the description is imprecise, it's the first time I use a bug tracker) I'm running ChatSecure for Android (info.guardianproject.otr.app.im version 14.2.3) and I cannot connect to my self-hosted XMPP server: when I add the account, the side panel shows "Connecting..." but nothing happens and I cannot chat/add buddies. My phone is a Samsung Galaxy SII (GT-i9100G) running CyanogenMod 10.2-201309-11-NIGHTLY-i9100G (Android 4.3) My XMPP server is ejabberd 14.07 on Debian Jessie with a certificate issued by Let's Encrypt, and it works well with other clients (e.g. Pidgin) but it has a somewhat strict security policy, so maybe I'm enforcing cipher suites that ChatSecure does not support? Here are some relevant lines extracted from my ejabberd.yml configuration file, follows the full ejabberd.yml file (with minor edits). Thanks for any help :) ----8<--------8<--------8<--------8<--------8<--------8<--------8<--------8<--------8<--------8<--------8<---- - port: 5222 module: ejabberd_c2s protocol_options: - "no_sslv3" - "no_tlsv1" - "cipher_server_preference" starttls_required: true shaper: c2s_shaper access: c2s ciphers: "EDH+CAMELLIA:EDH+aRSA:EECDH+aRSA+AESGCM:EECDH+aRSA+SHA256:EECDH:+CAMELLIA128:+AES128:+SSLv3:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!DSS:!RC4:!SEED:!IDEA:!ECDSA:kEDH:CAMELLIA128-SHA:AES128-SHA" - port: 5269 module: ejabberd_s2s_in s2s_use_starttls: required s2s_protocol_options: - "no_sslv3" - "no_tlsv1" - "cipher_server_preference" s2s_ciphers: "EDH+CAMELLIA:EDH+aRSA:EECDH+aRSA+AESGCM:EECDH+aRSA+SHA256:EECDH:+CAMELLIA128:+AES128:+SSLv3:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!DSS:!RC4:!SEED:!IDEA:!ECDSA:kEDH:CAMELLIA128-SHA:AES128-SHA" auth_method: internal ----8<--------8<--------8<--------8<--------8<--------8<--------8<--------8<--------8<--------8<--------8<---- ### ### ejabberd configuration file ### ### ### The parameters used in this configuration file are explained in more detail ### in the ejabberd Installation and Operation Guide. ### Please consult the Guide in case of doubts, it is included with ### your copy of ejabberd, and is also available online at ### http://www.process-one.net/en/ejabberd/docs/ ### The configuration file is written in YAML. ### Refer to http://en.wikipedia.org/wiki/YAML for the brief description. ### However, ejabberd treats different literals as different types: ### ### - unquoted or single-quoted strings. They are called "atoms". ### Example: dog, 'Jupiter', '3.14159', YELLOW ### ### - numeric literals. Example: 3, -45.0, .0 ### ### - quoted or folded strings. ### Examples of quoted string: "Lizzard", "orange". ### Example of folded string: ### > Art thou not Romeo, ### and a Montague? ### ======= ### LOGGING ## ## loglevel: Verbosity of log files generated by ejabberd. ## 0: No ejabberd log at all (not recommended) ## 1: Critical ## 2: Error ## 3: Warning ## 4: Info ## 5: Debug ## loglevel: 4 ## ## rotation: Disable ejabberd's internal log rotation, as the Debian package ## uses logrotate(8). log_rotate_size: 0 log_rotate_date: "" ## ## overload protection: If you want to limit the number of messages per second ## allowed from error_logger, which is a good idea if you want to avoid a flood ## of messages when system is overloaded, you can set a limit. ## 100 is ejabberd's default. log_rate_limit: 100 ## ## watchdog_admins: Only useful for developers: if an ejabberd process ## consumes a lot of memory, send live notifications to these XMPP ## accounts. ## ## watchdog_admins: ## -
